i just think its so funny that the javelin thrower seems invincible then u get to him and u slice him once and he dies and the dude doesnt even stop moving forward that killed him. :D
here are some tips for winning. be undead and buy the halberdiers as soon as the game starts. turn on the auto spawn and make them move in one line. attack the demons. next unit to buy is increased armor +2 then mages, mages have small armor thats why u need increased armor. after the undead take trolls then human alliance. good luck.
You can turn off the music (and SFX) in the title screen (look at the upper right corner of the screen), or from the ingame menu bar.
