Battlefield 4 Second Assault maps vs BF3 counterparts
The recently released Battlefield 4 Second Assault expansion pack includes four maps remade from BF3. DICE has added some cosmetic changes to the maps, adding some Levolution moments as well. The gameplay and map design and feel remains largely the same, while the visuals have changed.
For example, Caspian Border is now set during the Fall instead of during the Spring. Operation Metro has additional paths and chokepoints, Gulf of Oman has a desert storm rolling in, and Operation Firestorm is filled with burning oil pipelines. Check out a nice screenshot comparison between the new Battlefield 4 maps and the old BF3 ones.
