Looks like a good deal - Naturally, I have taken the plunge with WET.
Have bought several titles from Boomerang at good prices, like Prototype PS3 £10 and Ghostbusters PS3 £6.95 also. I dd see Fallout 3 there for £4.99 recently too.
I think that their ex-rental stock varies quite drastically from time to time.
WET is a highly-stylised third-person shooter that seamlessly blends gunplay, sword kills and over-the-top acrobatics to create the ultimate interactive action experience. The game allows you to shoot anywhere, anytime. You will have the freedom to shoot while running, sliding down ladders, sliding across the floor, or performing any number of acrobatic moves. Featuring an ironic mix of humour and violence, unique retro film visual treatment, and original 70's inspired music, WET is a third-person shooter experience unlike any other.

The job turns out to be more complicated than expected and the man who hired her isn't who he appears to be. On the run and looking for the man who betrayed her, Rubi is leaving a massive body count in her wake.
