There's still some tweaking that needs to be done before I can release the game. The game is being developed in Dos using QBasic 4.5 with the Direct QB Games Library. I'm doing this so that any one on Linux, Mac or Windows can play this game, all you need is DosBox.
The Game may have up to 5 upgrades and maybe 10 weapon patches, I haven't decided on the number of patches yet. I'm aiming to have a release version by the end of the week, but that's being optimistic It'll most likely be next week.
