Finally, the long-foreshadowed appearance of the alien invasion force. Keeping Alchemiss alive is fairly easy, just keep her off the front lines. The rest of your team should be more than strong enough to take on the alien threat, so as long as you keep Alchemiss from playing in traffic, she'll be fine. There are a total of four portals, and they continue to spew aliens forth until they are closed. Try to take out the Sergeants first, as they dish out more damage. Once you are done reaping the XP, and the coast is relatively clear, just click on the portal with Alchemiss and she'll close it, though it takes a few seconds. When you have closed one, red arrows will lead you to the next one. Praetor comes out of the fourth one, and makes a beeline for the museum. Cut him off, and hit him head on, and you should complete the secondary objective. Once you have smacked him down, interrogate him to end the level.
