Very good game for its time. Music changed with the situation you were in.. calm music when no action, but fast music when battle shooting began

Had potential but devs abandoned it, leaving many gameplay ruining bugs intact.

if you can get this for cheap, real cheap, get it. Get it for under $5 (I got if for 2.49). It's a one play-through type of game and it has issues.
