Respawn, aggro and teleport
- Spawners lie mainly at resource nodes and collectibles. Killed creatures respawn within 3 in-game days as long as no player is within 150 m.
- Prevent respawns: at least one powered building within 150 m of the spawner (foundations count with a smaller radius; belts, pipes, power lines, hypertubes and poles do not count) and kill the creatures present. Night spawners must have spawned and been cleared once. Every buildable has a value; once the surroundings exceed a threshold the spawner is disabled – a Miner is enough, a foundation is not.
- Creatures that stray too far from their spawner are teleported back (when no player is within ≈ 80 m) and get full HP (except Hogs).
- Creature Hostility (Options → Gameplay): Default / Passive (never hostile – Flying Crabs and Spore Flowers still hurt) / Retaliate (only attacked animals fight back).
- Vehicles protect from all creatures except Stingers, and since 1.0 also from poison gas and radiation.
- Creatures never attack buildings; buildings have no HP.

Weapon damage
Values from the wiki's “Combat” page. Weapon infoboxes partly list different numbers (e.g. Iron Rebar 13, Explosive Rebar ≤ 35, Nuke ≤ 200) – which one is current in the game is unverified.
| Weapon / ammo | Damage |
|---|---|
 Xeno-Zapper |
5 |
 Xeno-Basher |
9 (hits several targets) |
 Rebar Gun – Iron Rebar |
15 |
 Rebar Gun – Stun Rebar |

 Rebar Gun – Explosive Rebar |
50 (explosion) |
 Rifle – Rifle Ammo |
5 (hitscan) |
 Rifle – Homing Rifle Ammo |
3 + homing |
 Rifle – Turbo Rifle Ammo |
4 (hitscan, high rate of fire) |
 Nobelisk |
50 (explosion) |
 Gas Nobelisk |
5 poison/s × 30 s |
 Pulse Nobelisk |
5 + strong knockback |
 Cluster Nobelisk |
50 + 5 × 25 secondary explosions |
 Nuke Nobelisk |

Weapon details: the Rebar Gun fires single shots (magazine 1, 0.357 shots/s, reload 1.8 s); the Rifle has 100 m range, reload 3.2 s and full/semi-auto fire with magazines of 15 (Rifle Ammo), 20 (Homing) or 75 (Turbo). A standard rifle magazine does not kill a Cliff Hog (90 HP); a Turbo magazine (300 damage) kills every creature except Spore Flowers and Gas Pillars. Tactic against Alpha Hogs: Stun Rebar → 2 melee hits → reload → repeat (“stunlock”).
Remains → Alien Protein
| Remains | Source (amount) | MAM research |
|---|---|---|
 Hog Remains |
Fluffy-tailed Hog 1, Alpha Hog 3, Cliff Hog 5, Nuclear Hog 7 | Alien Megafauna – Hog Protein (1 Hog Remains) |
 Spitter Remains |
Spitter 2, Alpha Spitter 4 | Alien Megafauna – Spitter Protein (1 Spitter Remains) |
 Stinger Remains |
Baby 1, Alpha 3, Elite Gas 5 | Alien Megafauna – Stinger Protein (1 Stinger Remains) |
 Hatcher Remains |
Hatcher 1, Elite Hatcher 3 | Alien Megafauna – Hatcher Protein (1 Hatcher Remains) |
After the research all four remains behave identically: 1 Remains → 1 
Alien Protein in a Constructor. Since 1.0 remains are no longer fuel (previously 250 MJ). Alien Protein becomes an 
Alien DNA Capsule (sunk via a separate DNA counter – see AWESOME Sink), Biomass (protein recipe) or a Medicinal Inhaler (protein variant). Neither remains nor protein can be sunk directly. Tamed Lizard Doggos occasionally find remains too.
