New boss mania mod! Original idea by Lostdaniel Games, re-edited by Seb Mercenary, Stage by Wizard.
What's new? As I showed in the fifth Stage Test video, there are Popokarimus in the stage, Uroboros boss with script to remove them 3 seconds after they die. I removed Uroboros Mkono and Spiders to add Uroboros Wesker Boss.
Normally Uroboros Wesker stays in the stage even after dying, but with the script he's removed after that. He's very tough but rocket launcher is an insta-kill. Other enemies stop spawning when he spawns but this is fixed after killing him.
There are 6 Popokarimus, 15 Uroboros and 4 Uroboros Wesker in the stage. Proper use of rocket launchers is needed. I misused 2 of them but barely managed to use them all properly. Some bosses drop rocket launchers. One of the toughest boss mania mods.
Spawn is a bit slow but the difficulty is pretty high because of the new boss enemies. It's the best like this because a swarm of bosses is usually taken out with a rpg but in this stage you may need a lot of them. Plenty of ammo in the stage too.
Note: This stage will crash the game normally. It requires using GE Ultimate Trainer and enabling "Ignore Missing Files" option.
