Released in late 2019/early 2020, Build 4073014 represents the final "golden era" patch. It incorporates all major DLCs ( Fallen Ghosts , Narco Road ), the Special Operation 1 (Splinter Cell crossover), Special Operation 2 (Future Soldier), Special Operation 3 (The Rainbow Six Siege crossover), and dozens of quality-of-life fixes that earlier versions lacked. If you are looking to experience the Bolivian drug war in its most polished, content-rich state, this is the build you need.
