Halo Wars Message Board  

I've picked up quite a few throughout the game, but what do they do? I've scoured the webz but can't find an answer.

ok, here are all the skulls:

look daddy!-when grunts die, their methane tanks always shoot off.

grunt birtday party-grunts explode into confetti

cowbell-destruction physical magnified

wuv woo-scarab shoots rainbow beam made of pure love

fog-no minimap, final score will increase

sickness-all player units have 50% fewer hitpoints, final score will increase

rebel-sympathizer-non player units get 25% more hitpoints, final score will increase

rebel supporter-non player units do 50% more damage, final score will increase

rebel leader-non player units start with an extra veterancy level, final score will increase

catch-all player units recharce unit special abilities recharce in half the time, final score will decrease

sugar cookies-all player units have 50% more hitpoints, final score will decrease

boomstick-5% chance any non player unit blows up upon death with explosive area affect damage, final score will decrease

pain train-all player units train 50% faster, final score will decrease

bountiful harvest-supplies come in 25% faster, final score will decrease

emperor-all player powers recharce in half the time, final score will decrease

and thats all of them

no i know about the skulls which you earn if you meet the mission requirements, the black boxes are hidden throughout the levels that you play

The black boxes appear to unlock items on the HALO timeline.

yep found that out, thx for the reply though
