Last standing during a Wave (once).

Crybaby is an unlockable active Ability. It allows the Trooper to deploy a Next Wave without dying first, but only if he's the last Trooper remaining during the current round. The ability is triggered regardless of actual presence of teammates to be deployed. If multiple troopers survived on battle field and they all having this skill, Crybaby will be activated.
Good for outnumbering the enemy, has a similar effect to Martyr.
