"Classico" is often easier because you can see all your enemies, but if you're using virtual joysticks (which are more responsive and reliable than the accelerometer controls) that means you have dangerous blind-spots under your thumbs. Once you've settled on the least-bad control scheme, Xerox Docuprint C8 Driver's gameplay is fun but uneven (and often overly difficult because of the interface), as you fly around a tight rectangular screen, dodging and shooting at a variety of geometric-shaped menaces. The game's Survival mode lets you choose between dual or single joysticks (with the latter, you're always shooting), "Cruces" mode (enemies only attack at right angles), and a clever if difficult to describe Pacifist mode, in which you weave weaponlessly through enemies while trying to detonate bombs to defend yourself. The game's Campaign mode mixes up the control schemes, challenging you to stay alive for preset time limits across four different difficulty levels. There's a lot to like about Xerox Docuprint C8 Driver including its cool weapon upgrades and vibrant (if not unique) graphics and sound, and the game offers decent pick-up-and-play value for fans of multidirectional shooters. The age of the app's developer has gotten a lot of attention (he's only 15), but for a paid app, that's no excuse for having such an inconsistent difficulty curve, a partial English translation, and other rough edges in what's already an overpopulated genre. We hope to see improvements (and hopefully a price drop and an iPad version) in future updates. Xerox Docuprint C8 Driver

is a free, 2D arcade game in which you pilot a "stealth bomber" dropping bombs on a steady stream of tanks, trucks, and other vehicles. You hold your device vertically (portrait, not landscape), with your bomber moving back and forth at the top of the screen and your enemies moving left to right on the bottom of the screen. You move horizontally using a touch-screen slider at the base of the screen (or just touch and drag anywhere to move), and you drop bombs with an adjacent button. A set number of enemies, all with varying

speeds and toughness, move across the screen in each level, and you have to carefully time your bombs to destroy a certain number of them--without running out of bombs--to advance to the next level. Xerox Docuprint C8 Driver occasionally mixes things up (for example with bomb-deflecting whirlwinds or explosive missile carriers), but for the most part, the gameplay can quickly become monotonous--and hard to follow, given the screen's tight, portrait-mode proportions. That's only made worse by frequent animation stutters and inevitable crashes that completely erase your progress. Xerox Docuprint C8 Driver looks and sounds great, with nice audio and art direction, but that doesn't compensate for its instability and one-dimensional gameplay. The game also shows small advertisements between levels, along with a loud video ad on launch that will ignore your device's mute switch. Mus
