Notably, as Shephard watched Gordon Freeman's teleportation to Xen, he had the option of following him to the teleporter before it collapsed. Those are the letters that make up Corporal Shepherd's name. It is interesting to note that, in Portal, the background screen changes to reveal a keyboard with the letters A, D, R, I, N, S, H, E and a selected P. That appears to be true, as the only human character to appear on Portal is the female lead, Chell. Still, Gabe Newell commented that it is a 'total coincidence' and that Shephard does not appear in the game. Many think that Shephard could be the protagonist of Valve's game : Portal that has the main weapon, the Aperture Science Handheld Portal Device (ASHPD), which has the initials ASHPD - A drian Sh e p har d. He added that Shephard was really liked by fans and Valve when they finished playing Opposing Force. Doug Lombardi was interviewed by Eurogamer and said that although Valve does not have any secret projects on Shephard at the moment, they would like to use Shephard again in the future. Shephard does not appear in Half-Life 2, Half-Life 2: Episode One and Half-Life 2: Episode Two, but even so, he has a large number of fans, who have played these games, Gabe Newell hinted that perhaps some day would reappear. In the end, G-Man expresses a degree of respect for Shephard's ability, praising him for having the ability to 'adapt and survive all odds of death' that 'remind him of himself'. Shepard deactivates the thermonuclear bomb of the Black Ops, but G-Man reactivates her and Black Mesa is destroyed. Three months earlier, Shephard had seen G-Man during his recruit training. It appears that G-Man has an interest in Shephard, even before the Black Mesa incident. He never fights alongside or against Gordon Freeman. Shephard and Freeman's paths cross during the game, but only watch one of the climactic events of the original game. It is probably because he never received orders to kill them because his commander died when his Osprey fell, unable to inform him of his mission. Unlike the other Marines, he works with the increasingly suspicious scientists and guards to get out of Black Mesa alive.

However, during the subsequent events of the 'Cascade of Resonances', Adrian finds himself separated from his unit and tries to fight to survive. and then silence all the witnesses, especially a scientist named Gordon Freeman, the protagonist of the original video game. Marine Corps corporal assigned to Arizona's Hazardous Environment Combat Unit (HECU), is one of the men sent to the Black Mesa Resarch Facility to kill the aliens. Corporal Adrian Shephard is the main character and silent protagonist of Half-Life: Opposing Force, the first official expansion created by Gearbox Software for Half-Life.
