It's not often we get to talk about multiplayer games in conjunction with browser games, but Roadeo provides an entirely unique and enjoyable experience that requires two players and a lot of willpower. It's a racing game, but it's unlike any racing game you've likely ever played, as it requires one player to drive the car and the other to build the track -- at the same time.
There are two modes in the game: co-op and versus. In co-op, it's up to you and a buddy to get as far as possible. One of you will be controlling the car with the arrow keys, while the other will be controlling the track with WASD. You have to work together to get as far as possible, and to make things difficult, you'll have a randomly generated series of obstacles getting in the way of the track. As for the car part, you'll not only need to contend with your partners crazy track design, but also with picking up as many stars as you go along to boost your score.
The versus mode is similar in design and control, but you'll also be picking up power-ups as you go along -- things like oil slicks, meteors, fog and even pedestrian crossings will get in the way.
Either way, you'll want to find someone you really trust behind the keys, because it takes a little while to get into it. It's well worth the investment though, and by the fourth or fifth race, even non-gamers will have a knack for how to do it. We've never seen anything like this and it's ridiculously fun once you're into it. Visually, it's something of a mid-'90s homage, with geometric shapes taking up most of the screen and a rocking guitar track keeping you pumped to do well.
The point of entry is a bit of a bummer and the controls are a little loose, which is why it takes a little while before you can really get the hang of them, but you should stick it out because it's a rather rewarding experience in the end.
