Mid-mission events spawn inside dive rooms and pay out Expenite or rare yields. Most reward 250 Expenite on completion; the Transmutator window pays per-kill and the Prospecting Drone Hunt drops a Large Expenite Vein. Knowing the trigger signals saves runs.
A pressurized rock formation needs to be cracked with sustained drilling. The squad rotates on the formation until it breaks; ammo, drill heat, and time-on-target are the limiting factors.
Resonant pulsing tone + visible vein cracks
A sealed cargo crate from an earlier expedition. Survive the security purge timer while waves of Corespawn / Glyphids close on the container. Reward unlocks on the final tick.
Container hiss + Omega voice line
Move a heavy resource module from the spawn pad to a deposit terminal. The carrier slows the dwarf significantly -- escort and overwatch matter more than raw DPS here.
Visible crate marker on the radar
A buried geode field. Drill, carve, and mine through brittle terrain to expose buried nodules. Each fully uncovered geode pays out separately, so coverage scales the reward.
Buried-yellow dust pattern + ground tremor
A tagged elite (the research subject) spawns and flees toward an exit corridor. Kill it before it despawns -- typically a Hero variant of Glyphid or a Corespawn juggernaut.
Tracked tag + red status indicator
A heavy-mining vehicle (the Ram Hammer) chews through terrain on a fixed route. Escort it through the room while it deals with reinforced walls; protect from Corespawn ambushes.
Engine roar + waypoint marker
Spawn a Large Expenite Nodule, then activate the Transmutator. For 70 seconds, every kill in the room drops 8 Expenite chunks. Wave-spawn pressure is heavy -- bring crowd control.
Large green-glow nodule + Transmutator console prompt
Re-route an industrial coolant or feed pipe across the room. Carry pipe segments from caches to mount points, dodging Corespawn pressure. Squad coordination cuts the time substantially.
Sparks at the junction + flow-line stub
An old DRG vault locked with a Security Override timer. Hold the room while the cracking script runs. Hero enemies start spawning at half-time; vault contents pay out on full unlock.
Vault door pulsing red, sealed-vault icon
A Prospector drone (Data Drone) flees into the caves. Land three hits before it escapes the room -- on success it drops a Large Expenite Vein worth a small fortune.
Tracker chirp + drone visible at edge of room
