Chamber 18 – Portal

Portal is a generally challenging game, even when you get the hang of twitch portal shooting and moving around between portals. Chamber 18 puts those skills to the test though as it challenges you to hit timed switches, avoid turrets, jump on platforms and manage different portions where portals can’t be created. It’s a pretty stressful ramp up from the usual fare and makes us think GLaDOS wanted the player to die of nervous breakdown more than anything else.
