You lucky people! If you've been on the moon/living in a cave/dead etc etc for the past few years then you probably won't know how brill Targ Ren is, so please allow me (if I may) to explain. (Er, if you haven't then go away and have a bath or something.)
You have to make your way through five perfectly innocent levels, each one taking up about ten screens and with a different setting, with inhabitants including (beautifully animated) motorcyclists, thugs, pimps (with guns), hookers, skinheads, and even dogs. The general aim is to reach Mr Big, whose corks you have to pop as well (spookily enough). There are tons of moves, and you can pick up and use weapons which are lying about on the way round too.
But why is it so good? Er, well, it just is - probably because it's so playable. Mind you, it is a little easy to complete, especially when doing it simo two-player style (but then again that's much more fun 'cos you can beat up your friend as well, both on- and off-screen). If you haven't got this already, then what are you waiting for? Go out and buy a copy immediately. If you have, then why not buy another in case you lose your original copy (or something)?
