Dark Arena

The United Arms Organization constructs a top-secret training facility, codenamed Dark Arena, on a small, isolated island on an alien planet. Genetic splicing was performed to create dangerous Genetically Engineered Organisms (GEOs) that were intended to train troops, under the assurance that special security fail-safe systems would prevent the creatures from breaking free. However, in the summer of 2146, the failsafes failed, allowing the GEOs to overrun the facility and slaughter its personnel.

No sooner after this occurs, Angelina Bradshaw and her special operations team are summoned to the island to try and get things back under control, but all of her men are no match for the GEOs, leaving her trapped alone deep in Dark Arena. She manages to hide for a while to recollect herself and inform authorities of the situation before the GEOs finally find her. Unwilling to share the fate of her comrades, she begins to battle her way out of Dark Arena and must race against time to clear out a path to a hangar on the outskirts of the island and evacuate before a nuclear strike is called to destroy all GEOs as a last resort.

Dark Arena received "mixed or average reviews" according to video game review aggregator Metacritic. The mixed reaction was primarily due to poor enemy AI and uninspired level design, but the game was also praised for having many nice touches often not included in pseudo-3D FPS, such as a sniper rifle with zoom functions and a guided missile. Many people regarded it as a Doom clone, as it had similar gameplay and level designers were recruited from the Doom modding community.
