You are on a exposed station in space. Your goal is to avoid the missiles that are shot at you in slow motion. (And some strange missiles they are!) Some of the baddies are invisible and if you add that in to all of the mines flying through the air you get a whole new way of playing Marathon. The free floating mines, so to speak, will take some rather nifty manuvering or you will find yourself blown up in the air....This is if you choose to play it solo. A letter X design for a net game and could probably be pretty fast...there is a built in physics model and you could use the X for KOTH. Some good ideas here with what is possible with Anvil...
