Some ideas i came up with for ur mod.
1. Ion Cannon- Created from a becon ray, 3 long metal poles,and glass marble. Has high damage. Uses alot of crystal ore, 20 per shot.
2. (RL) Turret- Rocket Launcher turret - Made from 2 de/magnetizers, 2 long metal pole, flame thrower, advanced targeting beam, motion detector, another long metal pole, and a computer unit. High damage that shoots 2 rockets at once. 5-7 seconds between firing times. Lock on capabilities.
3. Atom splitter- Created from a replicator cell, food regenerator chip, energy unit, long metal pole, particle accelerater, and a radiator. Fires a atom into the enemis body that starts a chain reaction with his atoms that causes the enemy to over heat and and catch on fire and die. Like a poisin it takes around 5 seconds from being hit to take affect. Enemy blacks out and catches on fire and burns to death. Very gruesome. Ether is used for ammo. 10 per shot.
4. Battle Convoy Car- created from original vehicle, 2 powered accelerators, 1 anti-gravity device, 2 de/magnetizers, and a flame thrower. Can hold 6 people including you. Can have two turrets mounted on the top, may be overpowered.
5. Gray Alien- The oldest of the wizest aliens, also the strongest. shes big and nasty and especially fast. She can keep up with you so hopefully you arn't overburdened. Very High Heath and Great Damage. Lets out large cry when heath is below half that brings around 10 Dire reapers to aid her. Boss Alien.
I hope you look over some of my ideas and possible use them if your mod lives on. I recommend getting more people to work on it to keep it alive if you intend to.
