This is the best £10 I've spent in a very, very long time! (EDIT- no!!) It's fps with a hint of rpg thrown in, it looks good, plays well (NO!) and hosing down bandits with an AK or MP5 (sorry Viper 5!) is very satisfying (still true)... No downsides yet, but I've only played it for a few hours so far..
For £10 it's worth it to anybody!!
EDIT for downsides-
1/ After a while each in-zone area load will take several minutes rather than be almost unnoticed like when you start playing (game immersion killer) no micropause like Oblivion here!
2/ Patching the game invalidates all your save games and makes the trader items vastly more expensive to buy! Making a tough life even tougher...
Edited down from 5 to 2 stars (assuming the game can be finished before it freezes solid...)
