Does anyone know any good 2 v 2 and 3 v 3 rushes? I’ve been playing a lot of Halo Wars lately and have been losing a lot of games :(. So if have any good rushes (dont mind the race), Thank you!

triple brute- T2 brute rush into grunts/banshees/wraith single pump on a citadel while building brutes and chief upgrades.
Hard for anyone <40 TS to stop but once you start playing decent kids you’ll have to macro a bit better and can’t outright rush to win.
Seriously, just cheese every game until you start running into games where that doesn’t work anymore. You can worry about getting good when you start getting matched against players that don’t have brain damage.
If you want the standard build in a high level game, let’s say you’re Brute/Arby/Anders, then have your Chief go T2 and build Brutes/get Inheritance (as needed), Arby plays T3 defense unless no one on the other team is rushing you, then he can push up to deny expos/hit someone, while Anders goes R3 4-5 Hogs (your pick, I favor 5 to upgrade pads) and pushes up to deny pads/keep your Chief alive/force a recall. The common mid-game unit comp with Br/Ar/An is Banshees, either all-Arby or single Summit Vamp, and Gauss, respectively.
