So first weapons:
Bomb: do damage that last like a day. Cost a pretty large amount of tnt and uranium. Leaves a radiated area for a hour or so
Blasters: basically a blaster, but it causes a radiation effect. Uses up uranium or uranium pellets, a new thing
Turrets: basically same as blaster but a turret and needs regular uranium
Now for power:
Reactor: basically uses like 10 uranium blocks to create large amounts of power for a week. Needs water every few hours, and uranium blocks to run. If something goes wrong, it blows up, destroying everything within 50-500 blocks for a week ish and 5-50 blocks for longer, or forever. Also creates radioactive/radiation effect.
Open to suggestions on this
