I got it and it's a brilliant game.
The humour in it is well done and over the top, and the game itself is very fun to play, I think this is the best arcade shooter in a while, beating out ghost squad (but that's still a great game too) and I am putting it up there with my favorite, Time Crisis 2.
There appears to be a fair bit of unlockable content as well, some of which being dual gun mode, different weapons, directors cut mode, and more.
I haven't got far enough yet, but I hope there is a mode where there are limited credits, that would seal the deal for me.
In fact I was just planning to go and play that now, so I think I will.
