This edition of Doomguy's Warzone is all about the very best monsters from the 3 generations put together as one epic cast. To see who made the cut in All Stars!, check out the credit texture to see the names of the enemies that made it here.
This edition comes with an Skulltag version that has more enemies and is good for Deathmatch and other gamemodes that this port has to offer, including Invasion.
I consider all stars the hardest version of Doomguy's Warzone I have to offer for a good number of reasons. The normal gamebreakers such as the Whoopee Cushion are gone, some monsters are faster with more health, stronger attacks, and less frequent item drops to make this based on as much skill as possible. The Rifle is slightly stronger to equal the power of the M60, which isn't present in All Stars.
