this doom is different to the 1 i plade when i was 8 coz the sounds when you get shot where better and when he died also the layout. this doom isnt as good as the 1 i plade coz i plade on the ps1 versions 1 and 2 but this doom is a bit to well not to effend but crap. im only playing cos i miss the hole doom thing.
use ranged units on colossus and when he gets close make the units move back slightly and also if you have unlocked the king of hell do the same with him. set up goblins coz they slow him down alot. keeps this up if you find it usefull.
