An extremely engrossing single-level solo romp with an amazing attention to detail. Everything, from the cool physics tweaks, to one of the best ship incarnations to date, spells quality. Fantastic.
A full set of textures (and scenery, and the Borg Cube) from Star Trek. You can see a good representation by patching your Shapes file, and playing Arrival (the first Bungie level) with these shapes...
