Stryker is notable to be the only character in Mortal Kombat 3 to gain a new special move in Ultimate Mortal Kombat 3. He is now able to use his gun, which has incredible combo property.
Stryker arsenal are all related to modern weaponry and his police training. He can use his baton for two moves. His Rushing Attack consists of going straight to his opponent and if he connects, he will throw him with his baton. His other move is his Baton Takedown, which is a more damaging variant of a regular sweep. As a projectile, Stryker use grenades. He can throw them high or low, and there is no way to know which one he does at the beginning. His most infamous move is his Gun. He will crouch and shoot in front of him, pushing his character away and causing them to use their fatality scream. He has four combos, but two of them will cause his opponent to be launched in the air.
Against the CPU, Stryker is pretty strong. Using any launch combo, he can fire his gun while the opponent is airborne. Doing so, they will stagger back but stay in the air for a few seconds. Stryker than can run and perform a wide variety of move in order to do more juggles. It is possible to repeat a pattern which consists of a jump kick, a single punch and his Gun move. Outside of that, all variations of his grenade can be good counter to airborne opponents. Both of his baton move is mostly useless against the CPU, as they seem to be programmed to block it in most circumstances.
As a side note, Stryker Gun move is the only move of a non-boss character they will cause the opponent to use its fatality scream when hit. However, Goro and Kintaro will stay silent while Shao Khan will use his regular hit sound. Motaro is immune from the Gun move. This also applies in UMK3.
