Is this game anything like nethack?
uhmmm...
Well they both:
Run on Amiga
Are 2D
Explore a Dungeon
so you could say they are -anything- alike.
nethack = 1 player only
Total Chaos = 1 to 8 players
nethack = control only 1 thing, your character.
Total Chaos = control your character + every monster you summon +
every artifact you capture
After I played Total Chaos, nethack seemed really boring to me, because its more fun IMHO
to control wizard + army + air force, instead of just one little guy.
nethack has no animation
Total Chaos has many Amiga-quality animations.
In fact the gfx in Total Chaos are so much better
than nethack that it actually improves the gameplay. (Try pressing 'L' for LOS as 1 example.)
nethack has no music, at least the version I played many years ago.
Total Chaos has lots of beautiful Amiga-Quality music.
Total Chaos has realtime 50 fps Line of Sight raytracing. Nethack doesn't.
nethack is more of an RPG.
Total Chaos is more about the application of military power
using strategy and tactics.
Hopefully other Total Chaos players can give you more info.
