The original Trial Xtreme was a competent and enjoyable take on the bike stunt and obstacle course genre that's become so popular these days. The sequel, Trial Xtreme 2 HD, changes a lot about the look and feel of the game, and it's very different while maintaining the same basic gameplay.
This is the same game we've all played several times by now. Accelerate and brake buttons along with left and right leaning. A new addition to the mix is the ability to make small jumps, which is good for getting out of sticky situations. The default controls have you lean by tilting the device, though you can switch to buttons if you're more comfortable.
The first thing I noticed about this game is how much harder it is than the last one. They do not spend much time easing you into the game, and several of the early levels have very challenging choke points. The whole game is generally more difficult. It wouldn't be so bad if there were more frequent checkpoints, but unfortunately, you'd be lucky if there were even two. The completely unrealistic physics of the last game… well, they've somehow been made worse. There might as well not be physics at all. Though, it actually helps mediate the difficulty, as you can recover from bad situations in completely impossible ways, but it's hard to get used to. You can now flip yourself over so that your back is flat on the ground between the bike and the earth, and it doesn't count as a crash, for some reason. The game is still fun, but these things really took me out of the experience.
The visuals are greatly improved over the last game, now powered by the Unity engine. There is a lot more variety to the environments, lighting, and color palate, and it's a welcome change from the last game. Some levels just seem to be unfinished though. Several spots have badly done textures. That, or they aren't loading properly. This is a perfectly serviceable game, but it could really use some tweaks and fixes. This game can be yours for two dollars, and there is a free version to try out as well. Though, to be honest, I'd recommend the first Trial Xtreme over this one.
