Doom2.wad required. GZDoom included. It's a simple yet funny mod. It contains over 20 levels, several new weapons, monsters and stuff. Didn't take it too seriously, yet it is fun to play. it could be challenging sometimes but well, it's up to you to find how challenging this mod could be after all, I guess... PS: It's still my favourite mod even today.
Doom2.wad required. GZDoom included.
Do you dare to play trough 16 levels of weirdness, discover a silly but funny storyline and face against hordes of angry aliens with some powerful weapons? I guess you'll find out!
Plus, 7 levels of additional mayhem in the bonus episode: "The lost levels".
You can check how far you can get with the score (First episode only) and check if you can beat the record and earn some medals ;)
On a side note, try to really take care of your health, as unlike other games, you'll start plenty of health and then there won't be so much ways to fill it back...
The old mod i've made back in 2008, somekind of remastered with improved weaponry, dynamic lights, levels converted to UDMF format, Brightmaps, added extra lightning and more secrets...
Enjoy it as much as I did making it ;)
PS: New 2017 update! Now with less rabbits! XD
