 State of Decay: Breakdown
Thomas is called "The Father".
- Thanks to his Construction skill, Thomas provides additional options at the Workshop (if you have one). His mood also improves whenever you upgrade or build a Workshop. He has no special advantages in combat, but he could still choose any Weapon Specialization if he raised his Fighting and/or Shooting skill first.
- Thanks to the Leadership skill, the Cheer and Taunt emotes have additional effects for Thomas. Anyone can use the Cheer emote to try to gain Trust with allies and performing the Taunt emote makes enough noise to alert nearby zombies, but when Thomas cheers allies, their combat effectiveness increases for a short while, and when he taunts zombies he can actually draw them away from attacking allies. He’s also better at earning Trust in general and is more effective at resolving problems with community members who have fallen into a bad attitude.
- Thomas cannot be saved from death
