so i'm making an underground base like my previous missile silo, and i have the workings of a "secret" device that looks really cool... but i have nothing to make it do.

it looks like the device here

I was thinking it could open a "portal" but i am not sure how to make it look like a portal per se... without using actual portal and cray.

i was thinking it could mess up gravity with gpmp, but that might be a ittle over the top.

it recieves spark and after a while it is "charged" and could be stopped multiple ways- i kinda want it to do something "bad" so people can defuse it for fun. any ideas?

this is the fusion reactor going in said base. not quite finished. requires ambient heat. any ideas on how to switch out the hswc with anything destroyable? i have no ideas.

the reactor is primed to melt down if the cooling stops, so there's the destruction potential. i want the device to do some sort of "special" half life/sci-fi thingy. so the dest would have to be in addition to something else.

edit: this one is the fixed version, the last one was a buggy one :P

howabout a massive gravitational flux?
