Matt of RGN writes, "Dementium II as an FPS plays rather well, but feels very generic at times. The flow of gameplay, while slower at the beginning, is steadily exciting later throughout. The game performs well as a survival horror, ammo is not too scarce however. The game also adds aspects to effect the flow such as parts where you must flee or be put into a nightmare by ghosts. The game always adds a slight difficulty curve too which keeps the game fun, fair, and interesting although the combat outside of boss battles is rather unexciting due to its simplicity. Where the game goes wrong is in its repetition at points and how it forces the player to backtrack at times - which I feel detracts from the game and forcefully extends it."
