StarRupture's Forgotten Engine is a towering relic on Arcadia-7 that promises game-changing fast travel once powered up. You'll navigate its infested halls, battle relentless alien bugs, and craft essential components amid lore-rich audio logs. This guide arms you with every step to claim victory swiftly.
Preparing for the Forgotten Engine run
Stock up before heading out—you'll craft the Power Cell at your Basic Item Printer using Electronics (from furnace recipes) and Chemicals, looted or crafted en route if needed.
Pack dual weapons with top attachments bought via War Bonds from bodies and bases, plus stamina foods for 60-minute buffs and infection resistance. Approach post-star rupture to minimize outdoor bugs by skirting the edges, avoiding the central ruins.
Enter and navigate the main engine floor
Jump through the northern broken air vent.
Insert your Power Cell at the airlock door, and ride the elevator down.
Save immediately—head left into the main room.
Loot bodies and chests, then push to the Loading Area door.
Destroy blue glowing infection nodes to clear paths and reduce spawns.
Detour right for extra loot and backtrack to unlock prior blocks. Expect initial bugs—use mining tools to conserve ammo, retreat to doors for shield regen.
Activate power on the logistics floor
Drop stairs to Logistics—fight escalating swarms, prioritizing node destruction. Loot orange-glowing floor items in rooms like conference (IRO office logs) and restrooms. When blocked, veer right, clear tumors, and loop to the generator room below. Blast all surrounding nodes to power it up—this spikes enemy spawns but opens tech paths. Grab the nearby keycard from Loading Area Control Center's blue chest for blueprints and War Bonds.
How to craft the engine central core
Head upstairs via south/north stairs to Tech Stations (use keycard). Clear tumors through Storage Bay and Server Room for loot, then enter Tech Lab.
Step 1: Gather core materials
Collect 3 Stabilizers, 3 Generators, 4 Accumulators, 8 Electromagnetic Coils from prior floors—don't drop them.
Step 2: Access fabricator
Interact with Tech Lab machines; submit materials to craft one Engine Central Core.
Step 3: Secret LEM grabs
Check adjacent secret room for 40% dodge cost LEM, plus XP loot.
Final activation and unlock teleporter
Return core to Main Engine Control Center console.
It ramps up, halting at percentages for waves—early small bugs, later heavies (no crabs). Fight room-wide, using cover, doors for regen, and ammo sparingly. Completion unlocks Teleporter recipe—craft with 500 Quartz Building Material (research first), name uniquely for map-free selection.
