Alliance Duel (VS) & Arms Race: Score Both at Once
The six Alliance Duel days, what scores on each, how Arms Race phases work, and the overlap trick that doubles your points.
These two events reward the same actions. Do the right thing on the right day in the right 4-hour window and you score in both at once.
Alliance Duel (VS)
Your alliance faces another alliance Monday to Saturday. Each day has a theme, and the alliance with more points that day wins it. You need HQ 10+ and an alliance of 20+ members in your warzone's top 32.
| Day | Theme | What scores |
|---|---|---|
| Mon | Radar Training | Radar missions, stamina, drone combat data and parts, drone chip chests, gathering, hero EXP |
| Tue | Base Expansion | Building upgrades, construction speed-ups, Legendary trade trucks and secret tasks, survivor recruitment |
| Wed | Age of Science | Research and research speed-ups, Valor Badges, drone component chests |
| Thu | Train Heroes | Hero EXP, shards, skill medals, recruitment tickets, Exclusive Weapon shards |
| Fri | Total Mobilization | Training and promoting troops, speed-ups of all kinds, radar |
| Sat | Enemy Buster | Kills on your matched rival alliance (worth about 5× normal), speed-ups, Legendary trucks and tasks |
Day tips
- Sunday night: stack radar missions and send gathering marches so they finish after reset.
- Tuesday: finish buildings early and leave them gift-wrapped, then open them on Tuesday.
- Wednesday: time long research to finish here, and spend your badges.
- Friday: train low-tier troops in bulk earlier in the week, then promote them on Friday. A promotion scores the same as training that tier from scratch.
- Saturday: if you're weak, shield for the full day and empty your wall. Strong players should hunt the rival alliance only (empty bases score nothing).
Daily chests: 3 for everyone, 3 more with Advanced Rewards research, and 3 more with Super Bonus research (see Research Priorities).
Arms Race
A solo event in six 4-hour phases a day (starting at 00:00, 04:00, 08:00, 12:00, 16:00 and 20:00 server time). Phases rotate through Base Building, Unit Progression, Tech Research, Drone Boost and Hero Advancement.
- Each phase has 3 chests. Fill about three phases fully and you also get the daily big chest.
- Stage Swap lets you move one upcoming phase per day to a better time.
- Since late 2025 the phases line up with the VS calendar, and two slots a day also count for VS points.
The overlap trick
| VS day | Do it during the... |
|---|---|
| Mon | Drone Boost phase: stamina, radar, combat data |
| Tue | Base Building phase: open buildings, construction speed-ups |
| Wed | Tech Research phase: claim research, research speed-ups |
| Thu | Hero Advancement phase: hero EXP, recruit tickets |
| Fri | Unit Progression phase: training speed-ups, promotions |
The recipe: finish work early, hold it (gift-wrapped buildings, unclaimed research, queued troops), then claim it inside the matching phase on the matching day.
