This level involves travelling to the top via elevators. You will be facing mostly wall turrets, but they may be hard to reach (especially the ones on the left of the screen).
Enforcement Droid and rescue
When you reach the top, the president of Omni corp is pulled away as a hostage, and the final enforcement droid will attack.
It is based off the droid found in Stage 1, but this time, it has extra weapons. As it approached, it will launch mortars, and as it retreats, it launches missiles that need to be shot down. The missiles normally approach diagonally, allowing them to be destroyed easily.
When the droid is defeated, continue right, and rescue the hostage.
