Respawn AND Spectate

[Wilson543210 10]

I need help in making a way where I can have players respawn and be able to spectate and if they want, decide to come back in a reinforcing wave. Right now they just respawn and get bored from waiting around, not seeing the action, but I don't want them to be able to spectate and see enemies.

I know there is an ACE spectator for when you die, you can only watch friendlies I think.

Does anyone know how to help me here? We use ACE and MCC Sandbox.
