Homefront vs Portal 2
Homefront
Homefront lets you join the Resistance that's fighting against the bitter, ruthless and overwhelming armies of the Greater Korea Republic for the freedom of an occupied USA using guerrilla tactics. Experience an explosive first-person shooter gameplay as well as immersive vehicular combat in addition to experiencing the compelling story of the devastating cost of war penned by renowned author John Milius through interactive cut scenes. The graphics in the Homefront is also very well-done, presenting a bleak-looking landscape of abandoned and ruined structures, shopping malls-turned-detention centers, and walled towns filled with zombie-like people who just shamble around while the invaders stood guard with their rifles at the ready. Interestingly, Homefront even provides players with a large-scaled multiplayer mode where armies of different sides clash in an epic combat, though there aren't enough players around to get a match going.So, although the multiplayer aspect of the game is literally dead, the gameplay might be a tad bit too linear (invisible walls and the like) and that there are some glitches and bugs, Homefront still has an amazing campaign that will see you fighting for the independence of the USA against its Greater Korea Republic oppressors. It is worth the purchase, especially if you can get it at a discount.
Portal 2
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.
