How Research Works in Last War

Research in Last War: Survival Game is a time-gated progression system. Each research unlocks upgrades for troops, heroes, building efficiency, and combat. Research time scales dramatically with tier — early research takes minutes; advanced research takes days or weeks.

Research Time Calculation

Base research time is displayed before starting. The actual time is:

Effective Research Time = Base Time × (1 − Research Speed Reduction %)

Research speed reduction comes from: - Research Center level: Higher level reduces research time - Hero skills: Research-focused heroes have speed buffs - VIP level: VIP bonuses include research speed - Alliance technology: Alliance research reduces member research times - Events: Limited-time research speed events

Example: 24-hour research with 35% speed reduction: Effective time = 24 hours × (1 − 0.35) = 15.6 hours

Speedup Types and Equivalencies

Speedups come in time increments: 1-minute, 5-minute, 15-minute, 1-hour, 3-hour, 8-hour, 24-hour, and universal speedups.

Universal speedups can be used on any timer (research, construction, training). Time-specific speedups are limited to their category.

Conversion: All speedup types are equivalent in total time: - 60 × 1-min speedups = one 1-hour speedup = 60 minutes applied

There is no benefit to hoarding smaller speedups over larger ones — 60 one-minute speedups are identical to one hour speedup in value.

Research Priority: Combat vs. Economy

Early game: Economy research first - Construction speed, resource production, march capacity - Enables faster base development and higher-tier unlocks

Mid game: Military research - Troop attack, defense, HP - T3 and T4 troop unlock research

Late game: T4/T5 unlock research - Hours to complete individually; strategic speedup expenditure required

Speedup Efficiency Strategy

Rule 1: Complete research before season end Research carries over between seasons but benefits don't accumulate until complete. Don't leave 20% incomplete at season transition.

Rule 2: Use speedups on high-value long researches One-minute speedups on 2-hour research uses 120 speedups. Save for major research tasks (24+ hours).

Rule 3: Research speed buffs compound If using a research speed hero ability during a speed event, the bonuses multiply rather than add. A 25% speed hero during a 30% event effectively gives ~47.5% reduction, not 55%.

Rule 4: Alliance research donation Alliance research benefits all members — donating resources to alliance tech is high-ROI for shared military speed buffs.

Calculating How Many Speedups You Need

Speedups needed = Remaining Time (minutes) ÷ Speedup Value (minutes)

For 72 hours of remaining research: 72 × 60 = 4,320 minutes Needed using 1-hour speedups: 4,320 ÷ 60 = 72 one-hour speedups

Frequently Asked Questions

How does research speed affect research time in Last War?
Research speed reduction is applied as a percentage of base time. At 40% speed reduction, a 10-hour research takes 10 × (1 − 0.40) = 6 hours. Speed bonuses stack from Research Center level, VIP, hero skills, alliance tech, and events. Check your total speed reduction in the Research Center info before starting major projects.
What should I research first in Last War?
Early game, prioritize economy research (construction speed, resource gathering, march capacity). This unlocks higher-level buildings faster. Once your base reaches mid-development, shift to military research starting with T3 troop unlocks and attack/defense bonuses. T4 research becomes the late-game priority for competitive play.
Are universal speedups better than research speedups?
Universal speedups are more flexible — they apply to construction, training, AND research. Time-specific speedups have the same time value but limited application. Save universal speedups for whichever queue needs them most urgently. There's no time-value difference between equivalent speedup types.
How many speedups does it take to complete 7 days of research?
7 days = 168 hours = 10,080 minutes. Using 1-hour speedups: 168 speedups. Using 8-hour speedups: 21 speedups. Using 24-hour speedups: 7 speedups. If you have a 30% research speed reduction, effective time is 7 × 0.70 = 4.9 days = ~118 hours of speedups needed.
