Second Assault is the nostalgia expansion. Each of the four Battlefield 3 maps was rebuilt with a Levolution event: Metro floods its station, Caspian Border’s radio tower falls, Firestorm’s refinery and storage tanks become destructible, and Gulf of Oman gets a sandstorm that cuts visibility across the whole map. Capture the Flag arrived with it, and several Battlefield 3 weapons returned.

Operation Firestorm’s third version in Battlefield 6 and Metro’s enduring 24/7 servers both trace back to this expansion’s versions.

Metro 2014 is the game’s other grinder map and plays like Operation Locker with a flood. Caspian Border is the classic combined-arms Conquest map and the fairest of the four. Gulf of Oman’s sandstorm removes jets from the equation for a while and favours infantry and armour that know the map; Firestorm is a vehicle map with an infantry centre. Capture the Flag runs on all four and is best on Caspian.
