Research is one of the most important progression systems in Last War: Survival.
Unlike heroes or equipment, research provides permanent improvements that affect your entire account.
A player with better research can outperform another player with similar Power because their army receives stronger bonuses in every battle.
How Research Works
Research provides permanent upgrades for:
- Troops
- Heroes
- Marches
- Combat stats
- Resource production
- Account progression
Combat-focused research directly improves your performance in PvE, PvP, rallies, and alliance events.
Combat Research
Combat research is one of the most valuable investments for any account.
It improves important stats such as:
- Attack
- Defense
- Health
- Troop bonuses
- March capacity
These upgrades affect every march you send.
A strong hero lineup with weak research will not perform at maximum potential.
Research Categories
Offensive Research
Offensive research improves your army's ability to deal damage.
Common benefits include:
- Increased attack
- Higher damage output
- Better combat efficiency
This research is especially valuable for damage-focused squads.
Defensive Research
Defensive research improves your army's ability to survive.
Benefits include:
- Increased defense
- Higher survivability
- Better resistance against enemy attacks
Strong defensive stats help your frontline heroes and troops stay alive longer.
Health Research
Health increases how much damage your units can take before being defeated.
Higher health improves:
- Troop survival
- Battle duration
- Overall formation stability
Health becomes increasingly important during stronger battles.
March Research
March-related research improves your ability to deploy armies.
Benefits include:
- Increased march capacity
- Better deployment efficiency
- Improved combat potential
A larger march allows you to bring more troops into battle.
Research Priority
The best research order depends on your account stage, but combat-focused players should usually prioritize:
- Main combat bonuses
- Attack, Defense, and Health improvements
- March capacity
- Troop improvements
- Specialized upgrades
Improving everything equally can slow down your strongest progression.
Research and Power
Research contributes to Power, but Power alone does not show the full value of research.
Two players with similar Power can have different results because one may have:
- Better combat research
- Stronger troop bonuses
- Higher stat improvements
Research quality matters more than the Power number it creates.
Research and Troop Types
Your research should support your main squad type.
For example:
- Tank players should prioritize research that improves their main formation.
- Aircraft players should focus on maximizing their offensive potential.
- Missile players should improve the stats that support their damage output.
A balanced account is useful, but your main squad should receive priority.
Research Mistakes
Ignoring Combat Research
Resource and economy improvements are useful, but combat research directly affects battle performance.
Upgrading Everything Equally
Spreading resources across too many categories slows important upgrades.
Focusing Only on Power Gain
Some upgrades provide more real combat value than their displayed Power increase suggests.
Neglecting Long-Term Progression
Research takes time, but every upgrade creates permanent account improvement.
Improving Research Efficiency
To maximize research progress:
- Focus on your main combat path.
- Prioritize permanent bonuses.
- Plan upgrades before spending resources.
- Use research events efficiently.
- Avoid unnecessary upgrades when preparing for important milestones.
Summary
Research is the foundation behind a strong account.
Heroes, troops, and equipment determine how your army fights, but research determines how strong your entire account becomes over time.
Successful players prioritize:
- Combat bonuses
- Permanent upgrades
- Main squad improvements
- Efficient resource usage
A well-developed research system creates a major advantage in every type of combat.
