Oh, the hundreds of hours spent on this one... And if you find it too hard/slow to obtain some precious weapons/ammo, I guess that the good old bug is still around: The game actually runs separately the world/GUI and the actual battle. And the battle process communicates with the main process by means of updating a file on the disk when the battle is over. So, if you have a battle in which you looted a lot of ammo and/or alien weapons, you can replicate the results by launching any other battle and terminating the battle process with Ctrl-C. It will not overwrite the previous battle results, so the main process will gladly use them again :)
One of the few games where after playing the demo, it was "Shut up and take my money" - and that was nine months ago, and since then it grew much better. The blend of genres is a very good idea in itself, but the real value lies in replay potential. First of all, after you beat the game, you can go through it again with all the enemies being stronger and having nasty surprises in store, which forces you to adopt your previously working strategies. And second, there's a lot of room of self-imposed challenges in how are you going to play the game, that again makes the gameplay completely different. Most character classes also come with a skill tree that allows them to be shaped to different tasks - and the individual maps are so varied that there is no dominant strategy that would work well in all levels. Throw in savegame import/export and modding support - and there is really no reason to delay the purchase at all.
