Combat Strategies for Resource Acquisition

Maximizing Resource Collection Through Combat
In Last War Survival, the acquisition of resources becomes increasingly challenging as players progress beyond HQ level 20. What initially seems like an abundance of food, iron, and gold quickly diminishes as upgrade requirements escalate dramatically. This chapter explores effective combat strategies that enable efficient resource acquisition, a fundamental aspect of sustained progression in the game.

Zombie Hunting: A Primary Resource Source
We have identified zombie hunting as one of the most underrated yet effective methods for resource collection. The world map contains three distinct categories of zombies, each offering valuable resources upon defeat:
- Regular Zombies (Iron Head, Gluten, and Miser) – These specialized zombies drop specific resources: Iron Head provides iron, Gluten yields food, and Miser supplies gold. Each level offers first-time win rewards that should be prioritized.
- Doom Elite Bosses – These more challenging opponents require rallies but provide substantially better rewards. They guarantee first-time win bonuses that include all three primary resources (food, iron, and gold), along with Hero XP and battle data for drone upgrades.
- Event Bosses – Special limited-time bosses such as those in the General’s Trial event offer both immediate resource rewards and additional event-specific bonuses.
Rally Participation Strategy
Our research indicates that strategic rally participation represents a significant opportunity for resource acquisition. When joining alliance rallies, players receive guaranteed rewards regardless of the battle outcome. This system allows for up to 20 rally reward collections daily, creating a consistent resource stream that requires minimal individual stamina expenditure.
The optimal approach involves coordinating with alliance members to maximize rally frequency and success rates. By participating in rallies targeting resource-specific zombies based on current needs, players can focus their acquisition efforts efficiently.
Zombie Invasion Event Optimization
The periodic Zombie Invasion Event presents a concentrated opportunity for resource gathering. This event features increased zombie spawns and enhanced rewards, making it an ideal time to focus on combat-based resource acquisition.
During these events, we recommend prioritizing higher-level zombies that match current resource deficiencies. The compounding effect of regular drops combined with event bonuses creates a significant resource influx that can sustain upgrade paths for extended periods.
Stamina Management for Resource Combat
Effective stamina management forms the cornerstone of combat-based resource acquisition. Rather than depleting stamina reserves on random targets, this article advocates for a structured approach:
- Reserve daily stamina allocations specifically for resource-yielding combat
- Prioritize first-time completion rewards for maximum efficiency
- Target zombies that drop resources currently in shortest supply
- Coordinate stamina use with alliance events to maximize reward multipliers
By implementing this systematic approach to stamina expenditure, players can significantly increase their resource yield per stamina point used.
Combat Formation Optimization
The composition and formation of combat teams directly impacts resource acquisition efficiency. When targeting resource-yielding enemies, we recommend specialized formations that balance:
- Quick victory to minimize stamina consumption
- Minimal troop losses to reduce healing costs
- Appropriate force allocation based on enemy strength
This strategic approach ensures that the net resource gain from combat exceeds the associated costs, creating positive resource flow rather than merely redistributing existing supplies.
Resource Events and Hero Optimization
Resource Events: Strategic Participation
Resource events in Last War Survival represent critical opportunities for accelerating resource acquisition beyond standard gameplay. The Zombie Invasion Event stands as perhaps the most valuable recurring resource event in the game. Unlike regular zombie encounters, this event creates a concentrated period where resource gains can be multiplied significantly through strategic participation.

During the Zombie Invasion Event, we gain access to specialized zombies that not only drop standard resources but also provide courage medals—a special event currency. These medals can be exchanged at the trade store for premium rewards, with epic resource crates offering exceptional value for players facing resource shortages. The strategic approach to this event requires balancing immediate resource needs with the potential for larger rewards through medal accumulation.
An often overlooked aspect of the Zombie Invasion Event is the ranking system based on cumulative damage dealt to zombie bosses. This competitive element provides additional resource rewards based on final rankings, creating a dual reward structure that benefits active participants. Alliance coordination becomes particularly valuable during these events, as organized rallies can significantly improve individual and collective performance in the damage rankings.
Hero Selection for Resource Optimization
Our analysis of hero effectiveness for resource acquisition has revealed certain heroes provide substantial advantages when specifically deployed for resource-focused combat. Monika stands out as an exceptional hero for resource optimization, offering resource yield increases exceeding 40% when targeting specialized zombies such as Iron Head, Gluten, Mizer, and Doom Elites.
This advantage stems from Monika’s third skill, Treasure Hunter, which provides additional gold, food, and iron when defeating zombie enemies. This specialized capability makes her an essential component of any resource acquisition strategy. For free-to-play and low-spending players, prioritizing Monika’s advancement to at least 4 stars should be considered a fundamental early-game objective, as this unlocks her resource boost capabilities at meaningful levels.
While Monika excels in this specialized role, she represents part of a broader support hero category that includes Sarah and Marshall. These heroes offer complementary support abilities that can be strategically deployed based on specific resource targets and event parameters. Building a roster that includes these specialized support heroes creates flexibility in resource acquisition approaches.
Optimizing Hero Loadouts for Resource Combat
Beyond individual hero selection, the composition of hero teams significantly impacts resource acquisition efficiency. When constructing teams specifically for resource combat, we recommend prioritizing heroes with complementary abilities that enhance survival, reduce stamina consumption, and maximize resource yields.
The optimal hero loadout balances:
- Resource boost specialists (like Monika)
- Damage dealers to ensure quick victories
- Defensive heroes to minimize healing costs
- Heroes with stamina reduction abilities to extend farming sessions
This balanced approach ensures that each combat engagement maximizes resource gain while minimizing associated costs, creating a sustainable resource acquisition cycle.
Resource Event Calendars and Planning
Successful resource acquisition requires forward planning around event schedules. By maintaining awareness of upcoming resource events, players can strategically conserve stamina, speed-ups, and other resources to maximize participation when yield multipliers are highest.
We recommend developing a resource calendar that tracks recurring events like Zombie Invasion alongside personal resource needs for upcoming upgrades. This planning approach allows for targeted resource acquisition rather than reactive farming, significantly improving efficiency and preventing resource bottlenecks during critical upgrade phases.
Hero Advancement Priorities for Resource Optimization
The development path for heroes should be influenced by their resource acquisition potential. While combat effectiveness remains important, allocating advancement resources to heroes like Monika can provide exceptional returns on investment through increased resource yields over time.
For players facing persistent resource shortages, prioritizing the advancement of resource-specialized heroes can create a positive feedback loop: better heroes lead to more efficient resource acquisition, which in turn enables faster overall progression. This strategic focus represents a long-term investment in sustainable resource flow rather than temporary solutions to immediate shortages.
Base Management and External Resource Sources
Optimizing Base Production Facilities
In the advanced stages of Last War Survival, efficient base management becomes a critical factor in maintaining adequate resource flow. Our research indicates that upgrading production buildings should be prioritized within the broader development strategy. The food, iron, and gold mines within your base provide a consistent resource stream that, when properly optimized, creates a stable foundation for more aggressive acquisition methods.
To maximize base production efficiency, we recommend focusing research efforts on the economy tree within the tech center. Production-related technologies should be prioritized and upgraded to their maximum levels as soon as possible. This investment yields compounding returns throughout the game’s lifecycle, making it one of the most cost-effective long-term strategies for resource sustainability.
Strategic Survivor Assignment
The assignment of survivors to production facilities represents a frequently overlooked optimization opportunity. High-quality survivors can dramatically increase hourly resource yields without requiring additional player intervention. Epic survivors provide approximately 32% production boosts, while legendary survivors offer at least 50% increased production rates.
While acquiring high-quality survivors may present challenges for free-to-play or low-spending players, strategic assignment of available survivors can still yield significant improvements. We recommend prioritizing the placement of your highest-quality survivors in facilities producing resources currently in shortest supply, creating a dynamic resource management system that adapts to changing needs.
Intercity Trade Truck Missions
Intercity trade truck missions represent one of the most valuable daily resource acquisition methods outside of combat. These missions provide substantial food, iron, gold, and unique rewards on a regular schedule. The reward quality scales with both truck rarity and headquarters level, creating increasing returns as players progress.
Our analysis reveals an important strategic consideration regarding higher-rarity missions. UR and SSR missions offer superior rewards but attract more player attacks, creating risk of resource plunder. To mitigate this risk while maximizing returns, we recommend:
- Limiting UR and SSR mission deployments to 2 trucks per 5-hour cycle
- Assigning stronger defensive squads to protect valuable shipments
- Timing high-value shipments to coincide with periods of high alliance activity for better protection
This balanced approach ensures consistent resource acquisition while minimizing losses to opposing players.
Hidden Treasures Exploitation
The Secret Command Post’s Hidden Treasures feature provides access to diverse rewards including universal legendary hero shards, skill medals, speed-ups, and primary resources. This system requires seven types of treasure map fragments obtained through completing legendary and epic secret mobile squad missions.
To optimize returns from this system, we recommend:
- Prioritizing legendary and epic secret mobile squad missions
- Establishing fragment exchange relationships with alliance members to complete map sets more efficiently
- Focusing on higher-rarity chests for maximum resource returns
The accessibility of these missions makes this an excellent resource source for players at various progression stages, as the entry requirements remain relatively manageable even for developing accounts.
World Map Resource Gathering Optimization
Efficient resource gathering from world map nodes forms a cornerstone of sustainable resource acquisition. With up to four gathering squads available simultaneously, optimizing this system can create substantial resource flow with minimal active management.
The effectiveness of gathering operations scales directly with troop tier levels. Higher-tier troops offer significantly improved load capacities—tier 7 troops carry 1,600 resource units, while tier 10 troops transport 2,200 units. This progression creates a 37.5% efficiency improvement that compounds across multiple gathering operations.
Our recommended approach includes:
- Maintaining at least three active gathering squads at all times
- Targeting higher-level resource nodes for improved efficiency
- Upgrading troop tiers as a priority to increase gathering speed and capacity
- Rotating gathering targets based on current resource deficiencies
This systematic approach ensures continuous resource acquisition with minimal player intervention, creating a reliable background resource stream.
Strategic Base Raiding
For players comfortable with PvP engagement, strategic base raiding offers substantial resource acquisition opportunities. However, this approach requires careful target selection to maximize returns while minimizing potential retaliation.
Our analysis suggests focusing raids on unaffiliated players (those without alliance protection) to reduce retaliation risk. Additionally, thorough scouting before attacking allows for accurate assessment of potential rewards versus troop loss risk. This disciplined approach prevents scenarios where combat costs exceed resource gains.
The most efficient raiding strategy involves identifying resource-rich targets with minimal defensive capabilities. By maintaining this selective approach rather than attacking indiscriminately, players can establish a positive resource acquisition cycle through PvP engagement.
Arm Truck Collection Optimization
The arm truck feature provides automatic resource collection over periods up to eight hours, functioning whether players are actively engaged or offline. This system creates a valuable passive resource stream that requires minimal management.
To maximize returns from this system, we recommend establishing a regular collection schedule that prevents the truck from reaching capacity and ceasing collection. For players with irregular access patterns, strategic use of resource collection speed-ups can ensure the arm truck continues functioning efficiently during extended absence periods.
This seemingly minor optimization can significantly impact overall resource acquisition rates, particularly for players with limited active gameplay time. The cumulative effect of consistent arm truck collection creates substantial resource accumulation over extended periods.
