PvE & Aliens
The Selenite Threat
Which Moons Are Infested
Moons unlock in rings as the community explores them. The first ring (Inner and Major moons) is alien-free. Every moon in a later ring (Trojan, Inuit, Gallic, Norse, Irregular) gets a Selenite defense the moment its ring unlocks.
The Three Layers
- 1.Orbital Shield: attacked by Bombardment. When the shield hits 0 the moon becomes Contested.
- 2.Hive Garrisons: each garrison is cleared by a Garrison Assault. All must fall before the nexus can be attacked.
- 3.Hive Nexus: attacked by Liberation Assault. When nexus HP reaches 0, the moon is liberated (finalized within about 15 minutes).
All three are launched from the Battles hub, Selenite mode, with a Cruiser docked at a base you own.
| Operation | Min Troops | Rounds | On Victory |
|---|---|---|---|
| Bombardment | 5 | 5 | 50 + shield damage bonus; +50 Gold to you |
| Garrison Assault | 5 | 5 | Garrison cleared; Gold and shards (see Liberation Rewards) |
| Liberation Assault | 10 | 10 | 50 + nexus damage bonus |
Crew energy must be at least 60%. Bombardment has a 2 hour cooldown per player per moon. Losses deal no shield or nexus damage.
Difficulty
A moon's difficulty sets its defenses and who may attack it:
| Moon Difficulty | Campaign Type | Shield HP | Shield Regen / Day | Garrisons | Aliens per Garrison | Nexus HP | Nexus Defenders |
|---|---|---|---|---|---|---|---|
| Easy / Normal | Solo | 500 | 3% | 3 | 5 | 500 | 10 |
| Hard | Alliance | 2,500 | 5% | 8 | 12 | 2,500 | 30 |
The shield only regenerates while the moon is still Infested.
Extreme moons were retired on 2026-09-16. An Extreme nexus fielded more defenders than any squad could bring, so every Extreme moon became a Normal moon.
Alien Troops
| Type | HP | Armor | Damage | Ability |
|---|---|---|---|---|
| Drone | 80 | 0 | 4 | Swarm: attacks twice per action |
| Sentinel | 120 | 3 | 6 | Crystalline Shield: 25% chance to reflect damage |
| Ravager | 150 | 2 | 10 | Frenzy: +2 damage per 25% HP lost |
| Broodmother | 400 | 5 | 15 | Spawn: summons 2 Drones per round (max 6 active) |
| Hivemind Overlord | 1,000 | 8 | 20 | +30% damage aura for all aliens, regenerates 5% HP per round, 15% chance of an 8-damage psychic blast on every attacker |
Garrisons on Normal moons are Drones and Sentinels; Hard adds Ravagers. Nexus defenders are Ravagers and Broodmothers on Normal, plus Sentinels on Hard.
Selenite Campaigns
Solo Campaigns (Easy / Normal moons)
- ›No alliance needed
- ›Your first attack locks the moon to you
- ›You can hold one solo campaign at a time
- ›The lock expires after 7 days without damage
Alliance Campaigns (Hard moons)
- ›You must be in an alliance
- ›The first attack locks the moon to your alliance; every member can fight it
- ›Your alliance can hold one alliance campaign at a time
- ›The lock expires after 14 days without damage, and the Leader can abandon it at any time
- ›Solo and alliance campaigns are independent: holding one never blocks the other
Stalled Campaigns
On a Contested moon, if a campaign makes no progress for 14 days, cleared garrisons start to reform one by one. If every garrison reforms, the shield reignites at 50% and the nexus returns to full HP.
