+<h3>Trophies</h3>
+<p>
+The Pandoran War offers an optional achievement award system, in the form of trophies. Trophies are earned through various gameplay actions, such as completing missions, defeating enemies, and racking up stats. Earned and available trophies can be viewed in the menu from the title screen, the galactic map, and the challenges menu. A notification will be shown when a trophy is unlocked, sliding in from the left-hand side of the screen. So as not to interupt the game, potentially spoiling a hard-fought mission, notifications are only shown at certain points during the game.
