Although Prince Jay helped you with this, knowing that he's admin I'm probably not going to join this server. He's a very bad admin and his current boss battles server is terrible.
Pictures
- The Player Spawn.

This looks really great. Then I saw this -
- The Boss Spawn.

- The Hidden (Uncloaked).

How does that happen? The normals spawn look great and fitting to the theme and the boss spawn is just a baseplate with a yellow brick.
Stealth servers like this need to be thought out more. Even if the map looks fitting, it doesn't mean Deathbringer is appropriate for this. He doesn't seem to be. Sounds more like the Normals are just going to bunny hop around while firing their guns non-stop unless you use guns with ammo like Tier Tactical.
Half-Baked idea. The "gameplay" part didn't tell me very much how it work, only the basics. I have no idea what the classes are or what Deathbringer does. It's a stealth boss battles with one boss and the build seems to get sloppier and sloppier through out the pictures.
Who found that boss spawn acceptable?
I tried a similar idea, it was in Afghanistan DM called "Chompey Survival" where players had to find weapons across the map and then kill the boss - Chompey (who was just the Graboid playertype) while trying not to get eaten. It got very little players because the game wasn't even thought through.
I really hope this server won't be what I am expecting it to be. Please don't make it suck.
