Star Warrior 2 – Defenders is a shooter game developed by MyPlayCity, Inc. The game takes place in space, at a time when humans and aliens are at war. The aliens seek domination over the universe and it is up to the Defense Races to prevent this from happening. The human colonies are located at the center of the defensive ring, which is protected by battle turrets called Defenders. Players take command over these bases and do their best to defend themselves from the attacks of alien ships. In doing so, the rest of the human race is protected from imminent invasion. There are over 100 levels in this game, each with a mission that must be accomplished in order to advance to the next level. There are nine major missions to undertake; at the end of each, players go head-to-head with the Boss. Levels increase in difficulty, making the game more challenging.
The game features four levels of difficulty. New players can start in the Novice level and eventually try out Experienced, Professional, or Veteran. As the players progress through the game, they will encounter different types of enemies. There are more that 30 enemy units in Star Warrior 2 – Defenders. Different alien types can only be destroyed using specific weapons, so players must be careful to use the correct weapon for each. The alien invaders come from all directions so players must stay alert for any oncoming attacks. To help them along, the game provides 17 bonuses that help players destroy enemy ships more easily.
