There certainly are more stories to tell about Angel and the other members of the Resistance.
Earth is one very small planet in a very big galaxy, after all.
For the moment, however, the team is very happy to have wrapped this one up. The game is just single player. The world is very heavily populated with NPCs who are friendly, unfriendly, snide, helpful or whatever - there's a lot of emphasis on the character and world. The combat system in the game uses both hand to hand and ranged weapons. You've also got grenades, though they're not quite what you'd expect.
