There are some new additions and known changed to Dead Island's enemies:
- New mutated zombies have been added such as Grenadier Zombies, which throws grenades at the survivors.
- More zombies will be able to appear on screen at any one time, increasing hoard size and difficulty.
- Zombie respawning has been upgraded. Zombies will still reappearing in previously cleared areas, but will take into account all game information such as: whether the player is on a mission, the condition of the player, the duration since the area was last passed through, gameplay mode, etc.
