Looking at it from the perspective of StarCraft, doing a Blood Bath 1v1 against a bot its pretty straightforward. Adding another player to make it 2v1 has the potential to make it a lot easier, but there are moments where the bot could take out one of the players or at least pressure them enough to tax resources. Obviously, this all depends on the skill level of all the players/bots and their strategies.

Instead of the two players having their own base, they are running a shared base against a single bot. This makes it challenging as now the players are forced to communicate, or one can sandbag, but overall adds a bit of complexity. Though a shared base should allow one player to manage one aspect of the game while the other player manages the other aspect; such as building units and the base, while the other player navigates or harasses the bot.

It is possible to logically work together to get a better outcome, but the tools we have currently don't support that. I find this multiplayer approach intriguing as with the right formula could unlock a nice super power. As I would imagine having twice the mental bandwidth available such that more things are noticed or caught or imagined...
