The gameplay itself is tight, meaty and all around addictive (in a good way). This game also has tons of content for the price. There are around 5 episodes, tons of weapons, upgrades, perks, 3 difficulties, secrets and you get the entire OST for the game which totals around 100+ tracks (I personally love the OST for this game). Best $12 I have spent in a long time and I can see myself going back to this game over and over again to try out different character builds. If your an old school FPS verteran (or new player) and loved games like DOOM 1&2, Heritic, and Hexen then this game was made for you.
