I'd like a tank game with highly advanced assault drones as the "tanks".
The basis is interchangeable parts, you have a core, a CPU/camera feed, a mobility system, weapons systems, and cargo space (for stuff like ammo).
For instance, an early AGV would have
Steel Core I
HUD readout + NVG filter
Heavy Duty Treads
Steyr AUG + Magazine Loader
MagBox(20)
This is a mid-weight AGV with a basic HUD and night-vision capabilities, and one assault-rifle weapon that can be reloaded and has 20 spare magazines.
A later, specialized AGV would allow greater customization: parts can have their own slots for additional mods:
Heavy Armored Stable Platform
Advanced Zoom System + Radar Scanner
Quad-Leg Base (Stabilizer: Pile Drivers)
MSR + Magazine Loader + Camera Feed, Vector SMG
MagBox(20)
This AGV has a leg mod that allows it to drive spikes into the ground, becoming immobile but very stable. It has a zooming system and a radar, along with a reloadable MSR with a camera feed from the scope, and a stand-alone Vector that cannot be reloaded. The MSR has plenty of ammo in the MagBox.
A professional's machine, which would use the best parts absolutely covered in mods, would look something like this:
Heavy Armor Large Platform (Armor: Forward Guard)
Advanced HUD + Zoom/Enhance System (Program: Shake Reducer)
Quad Leg Base (Armor: Plating) (Movement: Claw Feet)
Stinger Missile Launcher + Shock Absorbing Holding System , Scar-H + Magazine Loader , Grenade Launcher + Grenade Loader
MagBox(20), HEDP Grenades (6)
Of course, this is a very heavy and somewhat slow AGV, and matches would have restrictions that wouldn't allow this anywhere near a newer player.
