Tom Clancy's EndWar

This trophy is heavily dependent on how the current War is progressing online. In Theatre of War a faction wins by either capturing a capital or owning a majority of the territories. There are only three capital territories: Washington, Paris and Moscow. Similar to the Blitz trophy, to capture a Capital city a faction must win a Conquest, Assault and finally a Siege mission on consecutive turns. If at any point the attacking faction loses one of these missions, the mission types reset. For this trophy, you need to be aligned with the defending faction, while your capital territory is available and your faction needs to have lost both the Conquest and Assault missions so that the Siege mission type is available. The Siege mission on a Capital city map is very rare and all effort should be made to earn this trophy when it is available, even if it means switching factions and losing progress towards Super Soldiers.

Once the mission and map are available, simply play it 20 times. Remember, you must be playing as the defending faction. Utilizing the three minute rule, have your boosting partner evacuate all his units. Repeat until the trophy pops.
