Portal Of Doom: Undead Rising

A distress call comes from a remote spaceship, and nothing answers back except silence and static. In Portal Of Doom: Undead Rising, you land on the station after the failed investigation and walk into empty corridors where the whole crew is already gone. The virus has started turning the personnel into undead alien monsters, and the Doom portal keeps spawning more creatures deep inside the ship. The story spans 33 short stages, so progress is saved after each completed section. You clear one zone, then move on to the next piece of the station, getting closer to the main portal and the final destruction of the infected ship before anything reaches Earth.

How to play?

Explore the space station room by room and move through tight corridors and maze-like paths. Fight undead enemies and mutants that block your route and patrol junctions. Collect weapons, ammo, and medkits from the environment to stay supplied for the next firefight. The shooter action mixes sci-fi gear with horror creatures, so every new weapon choice matters for surviving upcoming encounters. Follow mission clues shown for each mini-level and complete the listed objectives to unlock doors and new areas. Some sections require finding key items or terminals before you can open closed doors or reach deeper parts of the station. Track where enemies came from to notice unexplored routes, then sweep those zones for extra resources.

Destroy the smaller portals, then push toward the core Doom portal that feeds the undead rising on the ship. Finish all levels to shut it down and trigger the space station's destruction. Load your saved stage, tweak your weapon loadout on the fly, and clear the whole ship of monsters before the infection expands past orbit. Jump into this sci-fi horror shooter, test every corridor for threats, and see if you can wipe out the Doom portal invasion in one full campaign run.
