The game starts with Shepard’s helicopter crashing into the facility after he receives orders to eliminate the remaining Special Black Ops team, who were sent to cover up the incident. As Shepard makes his way through the facility, he encounters new enemies, including alien shock troops, Human Grunts, and a new race of aliens known as “Race X”. He also teams up with the friendly Vortigaunts and scientists who survived the catastrophe.

The game takes place parallel to the events of Half-Life, giving players a different perspective on the story. Throughout the game, players also get to see glimpses of Gordon Freeman, the main protagonist of Half-Life, as he progresses through the facility.

Similar to Half-Life, Opposing Force follows a physics-based gameplay, allowing players to interact with the environment and use it to their advantage. Players have access to a wide range of weapons, from traditional firearms to experimental alien weapons. The game also introduces new weapons, such as the Barnacle Grapple, which allows players to climb walls and traverse obstacles.

One of the unique gameplay features of Opposing Force is the ability to command and control squads of marines. Players can recruit and give orders to the marines, such as taking cover or attacking specific targets. This adds a strategic element to the gameplay and allows players to approach combat situations in different ways.
