A great diversion from the Tomb Raider series. Excellent co-op elements. If you want to introduce a girlfriend to gaming, this is the game as it includes local co-op and other appealing elements, and is not too difficult. Some challenging puzzles and the game is fast paced and full of action.
Excellent re-play value because each level will have multiple goals that you can achieve, like doing level speedruns, or colloecting all the skulls and powerups etc. Each goal will give you rewards, also, once you've played through all the levels, you get to keep all your artifacts/weapons that you obtained, making the second play through easier if you like, but you can also increase level difficulty when it gets too easy.
