I will play the Beta version but from watching that video it is probably not a game I will enjoy. Arcade racers have never been a favourite of mine.
First impressions for me are that I'd have to play it for a laugh and not take it seriously. It's very Mario Kart in that you can get raped from behind if you are in the lead. It pays to have a decent range of weapons (you can carry 3), some of which you can fire backwards.
If I took it too seriously I think I'd get frustrated that it's not always the best 'driver' who wins. But then that's not a bad thing, as it adds a different element to the gameplay.
It's not so much an arcade racer, as the racing is just a small part of it.
I'll probably give it a go, but I think I'm more likely to prefer Split Second.
