One of the best vanilla compatible megawads I played. The map 30 uses dehacked nazi and keens replacements. Nazis are plasma turrets and keens are rocket turrets. They work but the Sprite replacements fail to show at all. One room depends on a flag where the player can be telefragged or the spawn cubes fail to disappear to allow monsters to spawn in as a wall slowly lowers. Im playing though it and so far it plays well and looks amazing! I sure map 30 is the only one with trouble.
