Doom Walkers, Doom Elites & the Alliance Exercise Worm
Rally guide for Doom Walkers (DW), Doom Elites (DE) and the Alliance Exercise sandworm ("Worm Smashing"): rewards, strength needed and tips.
Doom Walkers (Doomsday)
- A server-wide event for players with base level 8 or higher.
- Usually runs every other Sunday, alternating with Zombie Invasion.
- Walkers respawn about every 4 hours.
- Starting a rally costs stamina; joining a rally is free.
- Walkers can attack bases, but never breach your HQ.
Rewards
- A first-kill reward up to 3 times per event.
- Server-wide achievements.
- A damage ranking for the top players.
Rally tips
Every squad in a rally needs enough strength for the Walker's level, or the rally fails. Cancel rallies with under-strength squads. Approximate squad strength needed:
| Walker level | Squad strength |
|---|---|
| 100 | 1.4M |
| 110 | 3.3M |
| 120 | 6.7M |
| 130 | 10.8M |
| 140 | 11.7M |
| 150 | 12.7M |
| 160 | 14.9M |
| 170 | 16.0M |
| 180 | 17.3M |
Doom Elites
- Elite zombies on the season map.
- Each level gives a first-kill reward once per season: the season resource, plus War Merit in Season 6.
- If you don't have enough of the season's resistance stat (like Virus Resistance), rally them instead of attacking alone.
- Rally trick: a low-resistance player starts the rally with one weak squad, and high-resistance allies join to take down higher levels.
- Level 20 Doom Elites give about 1,600 drone Battle Data per rally. Start the rally yourself for the full reward.
"Worm Smashing": the Alliance Exercise
From Season 3 onward, the Alliance Exercise (also called Marshal's Guard) features a Large Sandworm instead of the old tanks.
- Runs every 2 to 3 days for 30 minutes. R4s and R5s choose the level (40 to 90).
- Rallies only, 3 minutes each. Every point of damage is a point.
- Three stages:
- Above 70% health: just the Large Sandworm.
- 70% to 30%: small worms pin members' bases. Kill them solo, or teleport away.
- Below 30%: the worm is enraged and attacks bases, so reinforce each other.
- If rallies can't do at least half its health, drop a level next time.
