Basic Premise: You play as a team of 5 against 1 gigantic orgo with 50,000 HP and ARMOUR.
To win the game: You have to kill the ogro in 10 mins.
To lose the game: The ogro and his minions kill your team a set number of times (30). Or you fail to kill the ogro within the time limit.
How it works: You spawn with only the pistol and you need to find other weapons. All weapon points are protected by ogros minions (who are fairly weak but large in number). Once you kill a minion camp, you and your team can get the weapon they are protecting. Once you have enough weapons or feel confident you can kill the ogro, you can proceed to attack him.
If you die in the process, you will respawn with the pistol and have to go the minion camp to get weapons (only have to destroy the camp once). Overall, everytime you attack the main ogro, you chip away at this HP. So the basic objective is to cause 50,000 damage in 10 mins as a team of 5.
How the main ogro works: He walks around the map slowly. Uses attacks if players are near to cause damage (preferably in an AoE). He moves and attacks real slow. The twist is, if he hasn't been attacked in the last 1 min, he regenrates 50HP/sec (3000 HP/min). If he has taken damage in the last minute (no matter how minuscule), his regeneration stops.
How the coding will work: I don't know if it would be hard to code. All you need is a large slow bot with 50000 HP (new waypoints and a cool model would be great). For minions you can simply make a bunch of ratamata (or whatever they are called) spawn close to weapon points.
