MAP26: Hardcore is the second fun level the level in Doom 64. Like the other fun levels it is only accessed through the "Features" menu. The level music is the same as MAP10: The Bleeding and MAP24: No Escape .
The level itself is a boxed-in set of staircases, where the player must fight through a few waves of demons. The stage starts with the player in the middle of it all facing a rocket launcher, rocket boxes, combat armor, and a huge army of mancubi that the player must kill.
There are certain sections within the map where the mancubi can teleport, increasing the difficulty level somewhat. Once they are all killed, the player must advance through the stage until they finds a ledge they must leap to from the highest staircase, where a Megasphere, backpack, and a plasma rifle sit.
Upon collection of the rifle, a large army of arachnotrons will teleport in and two energy cell packs will appear on the ledge. The player must then leap down and reenter the fray. Once the player has killed every arachnotron, a cyberdemon, super shotgun and many boxes of shells will teleport into the stage. Killing the cyberdemon ends the level.
There are no official secrets in this level.
