The princip is simple…you can choose in a main menu whether you want to play a game for one or for two players (I wonder how is the second player controlled). After running the game you appear alone (or with a second player) at an abandoned space base holding a shotgun in one hand. It seems at the first sight you don’t need it. But this is going to change when you open a first doors by a key. A strange creature will run towards you and it’s plans with you are surely not honest. And in such situations you need your best friend – a shotgun (it’s worst when you have no ammo). So this is the start of the game. Levels are full of doors and keys – the doors are the main difficulty right after the monsters. Controlling is simple: arrows=movement, CTRL=shooting. Graphics is on quite good level (certainly for it’s age). The game is unfortunatelly not sounded – you hear just some „music“ which turned to be annoying after five minutes of gameplay. Despite it I can recommend this game to you.
