Force Gun

The Force Gun is an option in the final choice screen of the "Government Supported Private Investigator" ending of Infiltrating the Airship.

When chosen, Charles Calvin tells Henry that the earpiece he has been using the whole time can turn into a force gun at the push of a button. Henry uses it to shoot two Toppat guards (Benjamin Bourseious and Matthew Norbert) out of the Airship's cargo bay.

The Right Hand Man is alerted by the radio call made earlier by Matthew, and checks to see what's happening. He notices Henry in the cargo bay, and tries to shoot him, but Henry is quicker and uses the Force Gun to blast himself out of the ship to avoid getting shot. He lands safely in Charles's helicopter. The Right Hand Man realizes afterwards that the Toppat Clan is in deep trouble. This results in a success, ending the route.
