Traitor puts you into the shoes of a soldier of the Augustan Hegemony, forced to rise up against your former masters after you're ordered to do something you simply cannot accept. Explore the Aventinus Complex, complete missions, upgrade your ship and gather allies until you can overthrow the tyrants who have brought such misery to the people.

TIPS:
1. The game opens up after the 4th mission, when you reach the map.
2. Upgrades are available in shops on the map screen.
3. The menu allows you to see your stats, achievements and allies.
4. If a mission is too difficult, try playing a different one and upgrading your ship.
5. In some situations, survival is more important than destroying all enemy ships.

MEDALS:
If your medals aren't unlocking, this is probably because the NG server is having some hiccups. Try reloading the page and see if the preloader ad is being displayed. Then go to the in-game Achievements screen; the game will try to unlock any medals you should already have.
