Portal 2 follows in the footsteps of the award-winning original while continuing the story of Chell and Glados. Now with both single player and a 2-player cooperative mode, Portal 2 ramped up its game with a plethora of new, challenging puzzles, a storyline that's a lot richer than before, and more advanced and realistic physics that will govern your gameplay. Interestingly, the game also includes editing tools, allowing players to create their own puzzles which can then be shared for all to enjoy.
Portal 2 is definitely a much better game in the series and if you fancy giving this franchise a chance, you might want to jump straight to Portal 2. Sci-FiFirst Person
Survarium is a pretty decent MMOFPS that's focused strongly on team play and with a survival/ post-apocalyptic-theme. It offers a variety of different game modes, with a possible open world mode coming soon (hopefully), along with a several beautifully-designed maps. The game provides factions for players to join and plenty of tough missions to complete. Survarium boasts of having a huge range of realistic weapons as well as clothes that you can buy and equip. If you like the MMO version of games that are along the lines of Fallout or Stalker (after all, the developers are ex-devs of Stalker), Survarium is one game that you shouldn’t miss out on!
