Dark Arena has been labeled a Doom clone due to the similar look and play of the game
A training facility for soldiers was built on a small, isolated island. Genetic splicing was performed to create Genetically Engineered Organisms (GEOs), and when the security failsafes failed, the GEOs quickly took over the base. Then, Angelina Bradshaw (the main character) and her special operations team went to eradicate the threat, but they were pushed back into the center of the base, and Angelina is the only one left alive. She then knows that she has to reach a hangar on the outskirts of the island before a nuclear bomb goes off as a last resort to destroy the creatures.
The game's ending depends on the difficulty set by the player. If the player plays on the Easy difficulty, Angelina dies in the hangar (The "Bad Ending"). If the player uses Medium, she barely escapes (The Medium Ending). Completing the game on Hard will have her escape with ease (The Good Ending).
Dark Arena received "mixed or average reviews" according to video game review aggregatorMetacritic. 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.
