If blue, spend all credits on tazers and troll, otherwise boring.
If green, throw barrels and other (heavy) props around nonstop, otherwise once again zzzfest 3boring5me why am I playing this.
If red, try to kill people only to get rdm'd or tazed or propkilled but it'll be ignored because "ah well you were a traitor". You'll also probably get frustrated by green/blue not giving a fuck about the objective of the game, because doing so would be unbearably boring for them. (Note it's a catch 22 because for red rounds to not have the latter 3 problems, you rely on everyone else playing green and blue like braindead sheep who don't enjoy themselves).
