From the update:
That’s right, you might have 16 players in your team. We’ve got a hulk.
If we break this goal, we’ll produce both the Koris team and the Hobgoblin team.
Both teams are going straight into Frenzy maxed (16 Koris and 12 Hobgoblins + 2 enormous Hulks!!) - and, as a bonus for going through the $500,000 goal, Rampage backers can pick a Season 6 team of their choice free of charge.
