This was £59.99 the other day but has come down to £49.99. Being from movietyme it will likely be the USA version. Movietyme are customs friendly (they have an office in the UK) so there will be no import duty or VAT to pay.
You get the game and a second bonus disc with remastered cinematics from the first two games and some other stuff on the discs, the helmet and ammo magazine (to hold the game cases in).
USA version is region free
Down to £45.99
