Aero Fighters/Sonic Wings
In single-player mode, Keith survives the mission, unlike the more unfortunate Keaton. Keith is shown reunited with his wife and son, along with the reminder that there are "other battles to be fought." In cooperative mode, Keith is partnered with Blaster Keaton. Keith takes his missions much less seriously than Keaton does, often complaining about having to fight under extreme conditions. After the final boss battle, Keith crashes into the aircraft carrier upon which he and Keaton were meant to land, sinking it.
Aero Fighters 2 (Sonic Wings 2)
