Serious Sam II

If you miss the old days of Duke Nukem 3D and Shadow Warrior, Serious Sam-II is the way to go. Despite its shameless obsession with spoofing Duke Nukem Forever, Serious Sam-II is a worthy sequel to a very fun game. The action is even more frantic than before and the enemies are tougher, and to handle them, you need to chuck grenades simultaneously while firing away the primary weapon, which is a very welcome and innovative addition to gameplay. The level design is brilliant and very creative and even more beautiful than in the first game. You really gotta love how you are rewarded with an amusing cutscene each time you finish a level. The downside is that the level design becomes poorer towards the end. A must buy for FPS fans anywhere. You won't regret it.
