To Join MTF, it can vary depending on which branch you’re trying to join. Players that are MTF are more well known in the community, and also have experience on the server, For most MTF branches you’ll first need to rank up in Security before you can try out for MTF.

- As for Chaos Insurgency, there are two ways you can join. One way is escaping the Facility As D-Class, and finding your way to the Chaos Insurgency base, and asking to be trained. Now keep in mind that CI does not have to train everyone, so they may choose not to train you. Also, you may apply on the forums for CI here https://gaminglight.com/forums/forum/520-chaos-insurgency/
