Training Cap: increase
Research Steel: cost reduction
Research Gas: cost reduction
Use him early to do campaign mode, upgrading him to 71. Because Chester is an economy hero, his skills are passive. Because of this do not reset him once he reaches level 71, but upgrade him no further.
He should be enhanced to +5, which add +500 to the training cap, reduce research steel cost -100,000, and reduce research gas cost -50,000.
He can be obtained in Noah’s Tavern.
He can be obtained by Hunting Zombies level 1-9 or Zombie Lairs level 8-9
