Despite its simple graphic style—a throwback to the days of Tron right down to the “Recognizer”—Multiwinia’s simple, glowing shapes are oddly beautiful and downright hypnotic at times, making it all to easy to distract you from the explosive battles going on. As the name spells out, it’s a strictly multiplayer game, ditching the puzzle-combat structure of the original for straight-out battles.

Ambrosia Software is celebrating its 15th anniversary with a holiday bundle sale that features a collection of six classic Ambrosia games: Apeiron, Redline, Bubble Trouble, Darwinia, Aki Mahjong, and SketchFighter. Individually, these games would retail for $123, but they’re going for only $19 from now until midnight, December 24th.
