This is really just another episode of Half Life. You're Gordan Freeman in a spaceship instead of Gordan Freeman at Black Mesa. Its a really BIG spaceship though. The gameplay is just as smooth as Half Life's which of course is top notch. You get the usual weapons you get in Half Life.
Graphics are great.
There are few new models in this mod but quite a few new textures. Otherwise the graphics are identical to Half Life. It was a good idea to have this episode take place in a spaceship. Very professional I must say. No new music or anything.
