Do Titans have Allies?
Do Titans have allies, this screenshot suggests that they do. Notice at the Titans feet there seems to be some type of creatures supporting the Titan. They don't appear to be Scars, but something more akin to the Titan. Do Titans spawn some type of smaller stone creature like the Swarm Tyrant does spiders? If they do they may be harder than expected to take down, considering they have minions to aid them. This can add a boss fight in Free Play for four random players, or four friends. Maybe each Titan has a certain minion they can spawn/attract, maybe Scars will aid them. This will add a wrinkle to Free Play if this is the case.
