San Andreas has become an enemy wasteland, enslaving all it's residents. It's currently the beginning of 2018. Damon & the Recon Ops have been set into this never-ending battlefield owned by the foreigners with the objective to find out how to stop this. Damon & the team must go on various missions to collect information on the situation & rescue survivors being held hostage if possible.
While in these missions, B.A.S.E (Battle & Survival Entities) will attempt to drop packets of weapons, armor, medical supplies, or in rare occasions, soldiers to help you along special tasks.
You are equipped with the most advanced gear. This includes electronic visor, wrist panels, thermal vision, night vision, communication devices, scanners, database storage, etc.
