Double suicide grunt rush:
BO: T,WH
I like this strat a lot, scout for resources away from your base and as soon as the arby comes out get the resources next to your base with him and send him straight to the enemy base the quicker the better collecting crates a long the way that don't require you to detour. Also when your temple builds get a suicide grunt, and keep buying them when ever u get 160 resources, if done well and both of you do it, you attack a cov base because its weaker with 6-8 suicide grunts at 1:30-2:00 (teleported in) go straight for the center and boom the cov base is dead, they lose the game, just keep your arby there to stop them rebuilding for 1 min and one of their teammates is lost.
If they try and go for an early sheild, which you will see if you scout, just attack the centre with your ghost microing away from their leader, the sheild does not go up if you attack the middle.
Against a UNSC: do not go for the center first!!!! they should have about 3-4 buildings up by this time, just send 1 sg into each sp and use ur arby to finish it off, when only 1 building is left standing usually a reactor hit the middle, it goes down in about 3-4 grunts at this stage
Build more WH when you can, to try and get ur econ back on track, but it will be 2 arby against 1, u will usually always win, they will not have enought units to counter you in such a short space of time
To prove it works we played it on Laberyrinth against CtL Random and another CtL guy, they were arby and forge, we hit the arby who was CtL Random first, he was building a sg 3rd but we got their first with our ghosts to stop sheild just before our arbys arrived and destroyed him. This was before TU3 we retreated and I built hunters and my mate built banshees, we attacked about 4 mins later with a decent army against forge, and he was trying to gaus spam, but with 2 direct counters they got destroyed and he resigned. (The game was too long ago to give u the match stats link) but you can ask them if you don't believe me.
I went outside once, the graphics were ok, but the gameplay was terrible.
