"Call the reinforcements! I... I've bumped my little toe!"
Crybaby is an unlockable 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.
Good for outnumbering the enemy, has a similar effect to Martyr.
Note: This skill will make Last Mohican totally useless if paired together. However, a nice combo with Restless helps the crying trooper to revenge his enemy.
