During this period Isaac must destroy as many asteroids as possible. When Isaac crosses the hull and enters the firing pit for ADS Cannon 47 he takes manual control of the cannon while Hammond works to restore the ADS Grid's automated tracking system. Fortunately the section of hull he must cross is dotted with bulkheads that will protect Isaac from the periodic barrages.


The player will have to pass a Zero G environment (the starboard hull) to get to the cannon at the other side but use caution hundreds of meteors are still striking the hull and even a glancing hit will cause death. When all three sources are turned on the player will have to head to an ADS Cannon to control it until Hammond turns the defense system back on. The ADS Cannon's three main power sources are offline and Isaac has to turn them back on. Isaac makes it to the bridge, where he runs into his largest enemy yet: a Brute. This level sees Isaac trying to keep the Ishimura from being ripped apart from the upcoming meteor shower since the Ishimura's orbit is not decaying anymore.
