Super science magic always goes wrong. Project Temporality’s latest trailer neatly demonstrates the process by which any sort of exciting in-game tech inevitably becomes the only means of escape from the laboratories in which it was constructed and tested. Examples from the past include Magrunner’s magnet gun, Portal’s portal gun and Half Life’s crowbar. Temporality’s timeline-splitting tool can be added to the list when the game launches on Friday. This is what happens when Portal steps into a teleporter pod and The Swapper jumps in alongside it just as the switch is thrown. Mad bad science.
