Yes in some rare situation you could win with nothing but Guards or nothing but marines or hydras. (vs total newbies on BGH)Originally posted by SmashBros.Pro
I could win the game using nothing but Guards or nothing but marines, or Hydra's, but it won't always work. It's a good idea to get a mix of units and not just 1, but a stupid idea to get everything when you probaly wont need it.
Attacks using single units will be picked apart within seconds.
(and you'll probably die on your way to guards)
