SEF: Back To Los Angeles is an overhaul of SWAT: Elite Force and it aims to bring the experience closer to SWAT 3. BTLA features many gameplay changes to gear, movement and the scoring system. Most of the weapons have received an upgrade, from models to sounds, with many new additions to chose from — all featuring at least one variation to its configuration, from silencers to shortened barrels.
