This is supposed to be one of the better games on the PS3, which was considered to arguably be the best game in most of bundles that Sony supplied along with the console instead of giving us brits a pricedrop, then they eventually changed there mind.
Reputable online gaming review sites such as the highly respected IGN gave this First Person Shooter 91%, while receiving an average score of 86% based on all reviews, which is the 6th highest average rating game on the PS3, so it must be quite entertaining.
Now Shopto has decided to reduce the price to a very reasonable £19.99 including free recorded delivery with same day dispatch and if you go through Quidco, you'll also receive 4% cashback, making it just £19.19 all inclusive.
Hope that helps. :)
