Alien Mothership
Brad Copp1 / 2
A four-phase flying boss with destructible power cores, drone swarms and a crashing finale.
Description
Alien Mothership
A giant flying saucer that patrols the map like the patrol helicopter, then engages anyone it spots. Shoot out its three glowing green power cores to break it down; each one sends it into retreat behind a shield while it launches a swarm of drones that must all be destroyed before the next phase.
How it spawns
- Arrives automatically from the edge of the map: first one 30 minutes after server start, then every 2 - 3 hours (counted from the last arrival), only when none is already active and a minimum number of players are online. Arrival is announced in chat.
- Leaves on its own after about 40 minutes if nobody brings it down.
The fight
- Phase 1: rapid-fire laser guns, rocket salvos (some napalm) and a scorching laser sweep that sets the ground on fire.
- Phase 2: adds a tractor beam that lifts players into the air and drops them.
- Phase 3: adds orbital strikes on marked spots around every threatening player.
- Phase 4: the armour drops off the red reactor - destroy it to bring the ship down. It also fires a chasing death ray.
- Drone waves: after each core is destroyed, the ship goes invincible and launches drones (more with more players) that hunt everyone fighting it, spreading out across the group.
- It splits its attacks across multiple players, keeps hunting players who hide in cover, and rockets their position.
- When it dies it spirals down, crashes, and leaves five fire-locked heli crates, with the top damage dealers announced.
Useful config options
- Core health (5,000 each), reactor health (8,000), hull damage multiplier, damage taken per type.
- Spawning: auto on/off, first delay, interval between arrivals, quiet time after one leaves, minimum players.
- Flight: patrol and combat height and speed, lifetime.
- Drones: count per phase, extra per player, health, damage.
- Every weapon: on/off, the phase it unlocks in, damage, cooldown.
- Loot crates, health bar, map marker, global networking, all effects and sounds.
Commands (admins or alienmothership.admin; /ufo or /mothership)
/ufo spawn [edge]- spawn above you (or flying in from the map edge)/ufo remove- remove the nearest/ufo status- health, phase, state, and when the next automatic arrival is due- Server console:
ufo.spawn,ufo.remove
