30 minutes and I was sick of it
The combat feels so bland and boring when compared to the fast, fun, frenzied and funny mechanics we see in L4D2. It just feels like a shallow FPS lacking in content from the off. I can't see many sticking at it long and I don't think many people will grind out being a monster game by game as that aspect on your own is a yawnfest. £35-50 is a ludicrous price too - £15 tops and I'd still struggle to justify a purchase.
If only Turtle Rock were still operating with Valve and the HL dev kits. Shame Valve don't like the number 3 really - Half Life 3, Portal 3, TF3 and L4D3
