I played a few missions and was impressed with the variety of possibilities. The first mission put me on a planet at war with a group of invading aliens. Allied with the indigenous species, my goal was to infiltrate and destroy the enemy drop ship. At the beginning, I snuck by an ongoing battle between the two factions and fought my way through some guards to find a gate. Blowing up the gate revealed an enemy installation that holds a teleporter to the ship, which was behind a red force field. The head of the guard has the red key, which drops the force field. Once inside the ship, I had to navigate the corridors to find the ship’s reactor, and after destroying it I had 30 seconds to escape. Once I escaped and the mission was completed, I was rated on my speed and completion percentage. If the level is shared, times will be compared to other Spore players on a leaderboard. Sweet!
