Still got a week to go until Batman: Arkham Asylum and you've probably finished Wolfenstein and Shadow Complex many times over by now. Oh what to do, what to do? Well persoanlly I went nuts and downloaded a whole heap of demos to crack my knuckles over. So here's a quick run down of three demos you can download of the Playstation Network and Xbox Live right now to while away a few hours with.

First up is Wet. I've had some reservations about this game, as I think most people do. When sex is the primary push for a games marketing it's usually pretty safe to assume the game doesn't have anything else going for it. Tomb Raider remains the exception rather than the rule here with numerous other games featuring 'scintillating' and 'tantalising' femme fatal lead characters dissapearing as quickly as they appear. Bayonetta looks to be another exception to this rule as the game looks too bug nuts crazy not to play. Anyway, I'm babbling, now Wet (short for Wetwork, as in messy violent assassinations that get blood on you) has you playing with Rubi. The ass kicking hottie visible stage right. In a very smart move by the developers she's voiced by throaty cult TV star Eliza Dushku. If you want to know what the gameplay is like it can be summed up with the marketing pitch of 'Stranglehold meets Kill Bill'.

The main focus of gameplay is leaping and sliding around the place while shooting as many people as possible in slow motion, occasionally pausing to slice someone to ribbons with your sword. There's the requisite wall running, back flipping, table leaping. Health is granted by taking a swig from any nearby liquor bottles and certain areas have doorways that infinitely spawn bad guys until you climb to a switch and shut them. So in those instances you've got the choice of racking up your combo meter as far as you can or cutting your losses and moving on. You also get a go with the blood/rage/something mode where Rubi becomes super ferocious, complete with the Kill Bill rage music, and the world all goes red. Compared to other games with overload or rage meter sequences, this one looked pretty terrible the world was just a big red blood with people shaped red blobs running around in it. There's also a final level (it's a decent sized demo) that has you car surfing, leaping from vehicle to vehicle and trying to shoot bad guys. This was really an on rails shooting section with a bunch of quick time events thrown in, but visually it certainly looked very cool.

Overall the best thing Wet has going for it is the Grindhouse style they've adopted. The screen has a perpetually stained, grainy, old movie look to it and the characters are very exploitation inspired. The music is absolutely bad ass too, this is a game I would buy the soundtrack for. I do have a sneaking suspicion that beneath that filter and all that style, the game looks a little bit crap. The graphics look a bit dated and the animations where pretty jerky, not to mention the fact the bad guys all look kind of the same. Worth a try but don't expect anything jaw dropping.

Next up, Mini Ninjas was a bit of a pleasent surprise. The game was gorgeous, with the cell shaded characters of your ninja village dripping with sugary life. Animals play a large part in the game and in the demo alone you'll encounter a Noah's Ark load of wild life of all shapes and sizes from dragon flies to pandas. The bad guy samurai are actually forest animals transformed by magic and after you defeat them they turn back into rabbits, foxes and birds and scamper away. One of your Ninja magic powers allows you to possess any animal you come across as well.

The game is surprisingly deep and there's lots to do. It's almost like My First RPG, with your ninja collecting regents and items to make potions and even fishing for food. There are all sorts of combat elements in there from your basic hacking with your ninja sword, to using magic, super powered attacks, ranged weapons, sneaking. Like I said, it's a surprisingly deep game and a lot of fun to play.

If like me you've been bemoaning the lack of Sly Raccoon and Ratchet and Clank type games in this generation of war and survival horror Mini Ninjas looks and plays great and could usher in a new generation of games you don't actually mind playing with your kids. That's right Ubisoft, up yours and your Imagine Babies.

Last but not least, the Playstation store has a demo of Final Fantasy: Dissidea available and its well worth downloading it to your PSP right now, it's tons of fun. After being woefully unimpressed from screenshots like the one above and reading some less than glowing reviews of imported versions (the game has been out in Japan for months) I was ready to overlook this game. In fact I had overlooked it when my son Cameron (wise beyond his years) went and downloaded it anyway. It's his PSP I suppose (until Sony send me one of my own, wink wink, nudge nudge, save postage by throwing in a PS3 slim too).

You play through four matches in a kind of tutorial mode, with each match focusing on a different element of the gameplay. The actual setup is much more similar to Virtual On than your Tekken styled fighting game with a much greater emphasis on free movement. You can run up walls and leap to different levels, even take to the air and stay aloft with aerial attacks. An interesting feature of the game is that only one attack button damages health, the other one absorbs comabt strength, signified by those numbers you can see above the health bars in the screenshot. Your strength increases the damage you deal with your attacks and can lead to tug of war style battles between opponents. It's a different type of fighting game and a definitely worth taking a look at. Personally I thought it was great and will be angling to get a copy of this game as soon as I can.

In fact I'd say that the gameplay was enought to keep me interested without letting me control my favourite androgynous Final Fantasy characters. The demo let you play as Sephiroth, Cloud, Onion Knight, Cecil and a girl whose name I can't remember.

Look, don't take my word for it, get online and download these puppies, they're absolutely free.
