Mass drivers (basically long range tractor beams)

So like the mass drivers from mass effect.
(pretty much) Giant ship-sized interstellar tractor beams that push/pull things at hyperspace speeds.

-fast travel for small ships without a hyperdrive
-Works with all entities.
-can’t pull things through blocks (possibly also a con)
-yet the beam can still be fired through blocks.
-constant beam of hyperspeed.
-you can aim them like ship weapons

-expenssive advancement cost
-requires lots of resources to build
-use tons of cheterite and power
-uses additional power when a ship/entity/player goes through. (barely any additional power for players and entitys)
-requires level 30 (?)Codex_Mass_Relays

Actually they’re called Mass Relays.

Both names work fine
