The modern character design for just about every M-rated first-person-shooter and third-person-shooter video game. It involves a bald, ridiculously muscular alpha male (space) marine with a very manly chin. Usually the personality of your average badass war hero comes with this design.
Crysis. Gears of War. Killzone. GTAIV. Mass Effect. Space Marines. All big fans of the Bald Space Marines character design.
