Starcraft Remastered: 1 (Terran) vs 7 AI (Zerg), No units lost, Lossless
1 vs 7 Zerg CPUs as Terran with no units lost. This took many tries mainly due to the randomness of where the SCV ends up while walling off. Another trick is to keep harassing so no computer has enough resources to tech to queens and spawn broodling, as they seem to prioritise having an army over upgrades or teching.
Against Protoss lossless would be much harder, due to Psi Storm, Mind Control and Feedback.
