Good review -- that actually sounds like the sort of thing I'd be into for at least one or two games' worth (taking heed of your caveats). At least it's a nice variation on FPS. Pity it's not on Linux.
Thanks Katherine. Maybe it will come to Linux one day. The Windows version is still full of issues for a lot of people as far as the Steam forums seem to suggest so hopefully it will bypass those if it comes out on Linux.
