Best "vs. AI" ProTip I saw so far on Battle.net: Massed Ravens -> Massed Autoturrets. Buddy was chewing up Hard AI bases with it. No friendly unit loss! I think I'm gonna hafta practice that for the 7 Insane AI FFA, since its unlikely I'll be able to expand.

I've realized that NOTHING is cooler than blasting a base to ashes with a dozen Thors :)

there are a lot units that are not in multiplayer..
med evacs are your healers.. also marauders can stim.. and no science vessels.

edit oh moik, are you aware the the insane ai cheats... aslo I dont think you can support mass raven on one based.... to much gas

Yeah, mass marines/medivacs are basically my main base defense until I get the Ravens out. They do take a lot of gas, but I'm finding that with even just five or six I can keep the computer locked out of expansions. Once I get up to a dozen, it's fairly straightforward to eliminate their bases. Other than zerg, they rarely have any structural base defenses.

I'm told the Very Hard AI also cheats (extra minerals per gather).

that could work.. though zelot sentry will destroy a marine ball... and hope you dont get teamed up agaist.. I heard that insane as incresed havesting and shortened build times.. and that is were I see the problem with the build and then can just send wave after wave faster then you can regen energy... I would be most interested in seeing the replay after it happens or even obs the attempt.

Those frigging Sentries... I hate them. They really feel overpowered, but that's just because I never make enough Hellions. I assume Hellions don't count as ranged anyways...

they only feel overpowered if you make marines... just because they are low damage high fire rate... 1 ghost can render them useless... just in your case were you are trying to save gas... cause everything you need to stop it needs gas... marauder and their god blasted infernal friggin slow shells and good control with kill zelot sentry easy... unless they force field you to death lol I see your biggest problem is to servive the early game... even roaches will chew through marines fast... lastly never thought if hellions are effected by guardian shield.
