This is why we can't have nice things.
The nuts.wad series consits of large open areas spammed with so many monsters that you might actually lag.
I have actually managed to beat nuts 1 and 2 since there are methods of doing so but nuts 3 is IMPOSSIBLE.
The pictures are in order of the series.
Discuss.
P.S. inb4old Yes this is an old series but I really doubt half you guys even know what DooM II is.
