Portal 2 (2011)
Taking place long after the events of Portal:Still Alive, it is once again time for players to dive into the puzzles and mysteries left in Aperture Laboratories. Armed with only a portal gun and wit, players are thrown head on into the deep lore the labs have to offer, from Cave Johnson and Caroline, to Wheatley and GLaDOS. From portals, to gels and to murderous turrets, the tests have everything a gamer could ever be afraid of. Survival might be the goal, but it won’t be easy.
