Prepare for an out-of-this-world, 3-D flying experience with the remake of the arcade classic Defender. Defender sends you on a mission to defend your solar system and save the human race from alien invasion. In addition to space combat action, the game showcases elements of strategy, multiple types of humans to protect and use, ground units for players to defend and position, and bases to build and expand. Battling an onslaught of vicious aliens, players strategically pilot their ships through more than 14 treacherous missions spanning the solar system, executing dynamic tactical maneuvers such as barrel rolls, 360-degree loops, and spinning reversals in order to evade the enemy.
