NSKuber made a gamemode similar to what you've described, it's called Man Hunt.

I thinking you(or someone esle) can do a gamemode for Serious Sam Fusion.
I call it Serious Sam vs. Orks fusion.
It is heavily based on an unreleased gamemode(with the same name,but without the "fusion part at the end) for Garry's Mod.
Rules are simple;Only one player becomes Serious Sam while the others become the Orks from Serious Sam 2!
The Goal for Sam is to survive for 5 minutes,while the Orks try to kill him.
When time up or when Sam gets a certain number of frags,he wins!
As an Ork,you can choose 1 of the 5 classes,Gunner,Rocketman,Scout,Sniper,& Heavy Gunner.
Each class has their own parameters & weapon loadout!

dm dead !11!111111!1

I way more prefer playing DM rather than Campaigns, and I'll do my best to make people play it.
So no, I have way more DM mods planned, and I won't stop making those.

People who say DM is dead are part of the problem. :)

Pls no more DM mods! DM is DEAD!

Julia please, we can make it work.
Don't take the kids

DM is too dead to give it a try.
