RetroDefense - Develop a strategic defense network by placing and upgrading towers on a map, while invaders of increasing toughness attempt to penetrate your defenses.

Struggle to defend against six types of invader, each with a specific strength. You have a choice of ten towers that shoot a variety of things including lasers, missiles, power waves and freeze cubes.

There are four types of bonus you can earn, use them carefully to boost your tower´s power. All the towers can be upgraded to increase their range and damage, but at a cost. Lots of cheap towers, or a few really good ones? How you spend your hard earned money will determine your base´s ultimate fate.

The game includes a full fifteen maps of increasing difficulty, each requiring a different strategy to defend. It all adds up to tons of addicting game play and even includes a kickin´ soundtrack that changes as the game gets more intense.
