From Kickstarter Update #2 "These two tiles show the T-Rex and the Raptors at their most vicious, and are used for creating a more violent game where these two predators are more devastating: 1. The new Raptor Tile allows each Raptor, after it moves, to eat 2 Dinos and scatter 3 Dinos. 2. The new T-Rex Tile allows: 1) if T-Rex moves 1 area it eats 6 Dinos ; or 2) and if it moves 2 areas it eats 4 Dinos. This makes each of the new tiles a bit stronger and perhaps more desirable to choose than before, but doesn’t imbalance the game play."
