Comet Crash

Next to Welcome Back this is one of the easy Bionic Swarm trophies to unlock. On Area 34 there are a row of 5 Bombers on the lower left. Wait until the enemy Research tower finishes research on missiles silo's. The enemy will recycle the Bombers, replace them all with Missile Silos, and then immediately start building missiles. As soon as the missiles appear out of the silos build a Pulsar tower right beside one, and upgrade it two or three times. The Pulsar tower will destroy the missile silo, the missile, and cause and explosion destroying the four adjacent missile silos and missiles.
