TopWare Interactive announces Planets Under Attack is now available in stores in Europe, offering a boxed Windows and OS X edition of this space strategy game that was recently released on Steam. The box includes an optional Steam code, but all features of the game can be accessed without using Steam. Here's a description of the game:

The goal of this challenging space adventure is to conquer a galaxy of planets, while undertaking a multitude of special challenges. Take control of your mighty space armada, and wreak havoc across the cosmos, but choose your targets wisely! Conquered planets will net you income to expand your forces, but you must carefully weigh the pros and cons of attacking each planet, as timing and available resources are critical to victory. Above all else, you must keep a cool head. Enemies race to capture your territory as you hone in on theirs and multiple battles will rage on all fronts. You must make tactical decisions at every turn, from scouting your enemies and deploying units, to shoring up your planets’ defenses and knowing when to attack and when to defend. Strategic multi-tasking and a keen military mind will lead directly to unrivaled glory…while careless play will reduce your army to space dust.
