Just a suggestion, but it would be cool to see options for other colors besides red and blue in multiplayer, like grey vs. yellow, white vs. black, etc.
play flood. humans are a yellow-green and flood are grey.
They make MM contrasting colors for a reason. Red vs orange would suck.
think there are yellow vs green and orange vs purple somewhere, but I don’t know if those were changed back to RvB in multiplayer.
