One thing that we are very proud of is the AI of the Meccaryns. When you start the game your buddies don t do very much else than stand their ground and shoot. As the game progresses they will get smarter and smarter and eventually you will see them taking cover, circling the enemy to get a better shot and more. You can also give them orders such as stand your ground, order them to move to a different place and more. I would imagine Sea Reapers would have a spell of sorts to provide this.
Reapers have a health vial, plus they can slowly gain health back by swimming in the water.
Also, they both get health back when they enter one of their shops. Kabuto gains health by eating things. I d say that this is unlikely because so much has already gone into these three races. There have been major gameplay issues to address with these 3 uniquely different races - they re not just the same character with a different graphic. This said, you would definitely be seeing new characters in Giants 2. . .
