hiya, just want to propose some interesting items/effects:
1) Visual display of jetpack fuel (some small bar) indicating how much fuel you have left without opening inventory.
Why: I freaking love jetpacks, but hate falling out of the sky on longer high use trips (AEther mod I am looking at you)
2) Isotope Accelerator Core
Wtf is that? : made from something like a depleted-cell+uran-cell+isotope-cell and maybe some electronics. generates 1.0x the heat of a uran cell. and .5 the power. when placed next to uranium-esk cells it causes a double pulse rather than a single pulse. 75% chance of leaving a depleted accelerator core behind on death (? maybe). Doesn't pulse by itself
3) Isotope Inhibitor Core
same as the Accelerator core but causes adjacent to lose a pulse. Generates 1.5x uran heat, but doesn't pulse by itself.
4) Uranium mini-gernade
made from a single near depleted uran-core and a sticky tnt = bigger explosion tnt;
5) Heat detector
Use on a reactor to get its hull heat. It would be good for any reactor that's not a Mark I-EX and has a cycle time.
