1. I suggest to add 2 chems for IPc's that would be as easy to make as salline-glucose and would have no OD.
Ion repulser - For as long as it's in IPc it makes them and their equipment invulnerable to EMP. With that SMART IPc's would no longer be as easy as one click to kill.
That chem is a must have for machine sec. officers yet it doesn't exist, yet!
Energy amplifier - Makes machine people regen stamina very fast and recover from stuns a bit faster but also drains energy. (IPc officers are now doom of swarmers!)
2. Roboticists should be able to make upgrades to IPc's! Genetics for organics, robotics for IPc's. Here are some ideas.
Improved hull - Slightly more ressistant to all damage than organics.
Impact ressistant hull - Ressistant to melee attacks and thrown items.
Lightweight material hull - Makes machine people move faster without any other changes.
Improved energy battery - Simply more energy.
Experimental energy battery - Much less energy meaning constant APC charging but immunity to EMP.
Extinguisher module - Works just like recharging wire. Except it's extinguisher and needs to be refilled with water. (Or something nasty)
Storage module - Works just like storage implant but it can be emptied simmiliar to stripping (click drag menu) and holds a bit more.
Magnetic feet - Magnetic boots.
Legal for security only upgrades:
Space ressistant hull - Ressistant to extreme temperatures and immune to space.
Heavily fortified hull - Turns machine people into slow as dionas heavily ressistant to all damage tanks. They can no longer be pushed down by hand or pressure. The hull will replace uniform since you're too big to wear it now, you can still hold ID and belt as if you had uniform. (can still be disarmed or tased).
The Anti-Fall - Makes IPc immovable and unstunnable, requires ground to use. Takes about a second to attach your self to the ground. If moved process stops.
Energy gun hand - Energy gun with disabler and kill modes. Replaces hand. It uses IPc's energy to shoot. (Thus useless on organics)
ZGPS (Zero Gravity Propulsion System) - Works just like a jetpack but it's thrusters on arms and legs, can be turned on or off, uses IPc's energy.
(There would be slots for hull, battery and feet. Rest can be installed freely. Common sense.)
If examining IPc, a message saying which upgrade IPc has appears. If non, it just says standart hull.
If a criminal has the upgrades, RnD can print "Reverter" so security can use it to strip an IPc off of it's upgrades.
All can be balanced with required materials and research level.
Difficulty in coding varies depending on what would be implemented, if all then ofcourse very difficult.
Sprite work wouldn't be necessary but it would make it much better (mostly for hulls).
Whew, thats a lot, hopefully just at least one thing gets implemented, because i really like IPc's, but they are so vulnerable that it's painful.
