I am designing a "Mod" with Mechs. There will be a Rocket Mech, a Grenade Mech, and a Chaingun Mech. Now, the whole Idea is to introduce Mech fighting into the game, using the excellent halo physics engine.
The Mod is actually going to be a Map Mack. 4-5 maps. One will be based on A desert theme. One will be based on a Snowy theme. One will be based on a rainforest theme. One will be based on an Urban theme (new mombassa/earth city). And there may be another one, but it is still in development.
I have already completed modeling the desert themed map, and have et to texture/compile it. The rest of the maps have yet to be modeled.
The mechs. Oh the mechs. They are a PITA. I suck at modeling that kind of thing.
Ok, here is the whole Idea of the Mod.
Title: Mech assault.
Idea: Each player spawns in a room in which they can choose which teleporter to go through. one teleporter to the Mechs, one to the outside. There will also be an armory right next to the spawn room. There will be a door behind where the players spawn so that they can go on foot.
Each mech has a special attribut to it. The Chaingun mech will be fast, the Grenade mech will have a "medium" speed and the rocket mech will be slow.
The chaingun mech fires 1 chaingun per mouse button. And can fire forever. (ie, right mouse fires right arm gun and left mouse fires left arm gun.)
The grenade mech will fire both arms with the right mouse button and the secondary fire will fire a grenade that has a bigger explosion. the primary fire will take 4 seconds to reload, and the secondary fire will take 8 seconds to reload.
The rocket mech will fire each arm with the primary fire, which shoots two rockets. the secondary fire shoots a tracking rocket that does less damage then the regular rocket. The primary fire will take 4 seconds to reload, and the secondary fire will take 8 seconds.
MECH POSSIBILITIES:
Sniper mech. Faster than the Chaingun mech. Has Jump Jets, and fires sniper bullets. Has a 2x zoom, a 4x zoom, and a 10x zoom. takes 4 seconds to reload. Each bullet is fired at the same time.
Laser Mech. As fast as the grenade mech. Does not have jump jets. Fires the Rail Gun projectile, one arm at a time. Right mouse fires right gun, left mouse fires left gun. 4 second reload time.
Needle Mech. FAST. Faster than the sniper mech. Jump Jets. Fires needles at a very fast rate. LMB fires left gun, RMB fires right gun. 60 needles per gun, reload time is 6 seconds. Anti Infantry Mech.
Mine Mech. Fast as Grenade Mech. Drops two mines as primary fire, shoots a mine as secondary fire. 3 mines to kill a person in a mech, 1 mine to kill a person on foot. Reload time for both is 4 seconds.
Tank Mech. Slow as rocket mech. Fires tank shell. Gun is mounted on top above cockpit. 4 second reload. Secondary fire is a sloping tank shell, kind of like how the fuel rod gun does not fire straignt, but goes up and comes down.

Active Camo Mech. Fast as the Chaingun Mech. Primary fire activates the active camo and deactivates it. Making the mech invisible/noninvisible. Secondary fire is to open and close cargo hatch. Cargo hatch can hold troops, or a vehicle up to the size of a tank.
Vehicles:
Mine Truck. Lays mines with primary fire in its tracks.
Modified worthog. Fires Armor Piercing rounds instead of regular rounds. Will take out a mech with 20 rounds.
Turret. Mannable, fires AP rounds. Takes a load of damage before the player is destroyed.
All other vehicles will be default.
There will be different Mechs with the different levels. I will Update this post with each change I make.
Please post ideas.
PS: I would also appreciate any help with this project. I need experienced Mappers, and maybe a modeler. Some one who can make textures.
