Beta version 2.3 of Eternal silence is out guys. Its an HL2 Mod which is set in space and is a conquest game except to get to the enemy's base you have to fly a space craft over to it or take down the enemy space craft flying around your base. At the enemy's base you leap out of your ship and start mowing people down with guns and flamethrowers.
Its great fun once you have got used to the controls although flying is hard unless you invert the pitch in the controls section of the options.
