Space Hulk is a depiction for Mobilephones of the Warhammer 40,000 board game.
It is played top down, and is turn based. It does not include any of the expansions of the original boardgame. Sadly there is also no Level Editor
The Features are :
You can play as either the Terminator Marines or the Genestealers, but nothing else.
Turn based strategic/tactical gameplay (as in the original board game)
The turn based modes offers only a multi-mission campaign for either Genestealers or Marines.
