theres a red and a blue team and they both have a flag.go to the other side and get the flag then bring it to your side and put it on your flag base..there is no changing teams, if you want to change teams, leave the game and join back, you may end up on the same team or different.only and only my friends can go through my laser doors,so if u want to go through them prove that that you are good enough of a fighter to.this is like a war.I hope you like it.
