This is like in Mario Party 2 or Mini-Game Party where you have to choose 1 or 2 chicks and avoid ugly chicks.
There will be a line of Kerrigans, infested and normal. When it's your turn, your objective is to strategize and either choose the front Kerrigan, or two front Kerrigans. This ultimately screws the person behind you or screws the person two spots behind you (if you're collaborating >:) ). Make other people choose the infested Kerrigans (ugly chicks)!
