This game is undeniably incredible. I finally "beat it" (Team Dwarven Bulwark!), and yet can't wait to play more. DarkGod has delivered us a truly great experience. If you're not sure if it is "worth your $7" (it's value is far greater), you can play for free! You can download it from TE4.org. Be sure and get the "full" version with music (which is magnificent). I believe all versions come with the wonderful Shockbolt tileset (and of course ASCII mode also).

I strongly encourage everyone to donate to at least "Gold" status.
Silver = 6€ and 15€, Gold = 16€ and 30€, Stralite = 31€ and 60€, Voratun = 61€+
