You might be tempted, especially after your first run-through, to speed through the initial tutorial zone as fast as possible (and I wouldn't blame you!).  But you'd be missing out on the start of one of Champions' fun features, the Perk system, which gives you perk points for various achievements, which can then be spent later on goodies (Monk's note: New costume pieces, different looks for your powers, etc).  The tutorial has a number of perks to nab, which are unobtainable once you leave - so be sure to get them on your way!  A few of the "secrets" include:

- Jump on top of one of the first crashed alien vessels ("Red Bug Down" perk)
- A cat crate hidden among the rubble that starts a quest ("Reggie's Owner" quest) - A mission ("Batter Up") to save Foxbat, who's trapped under rubble by a fountain - as an added bonus, you get to keep Foxbat's gun when you finish the quest!
- A mission to help trapped civvies you get via radio when you're at an area near the second quest hub in the zone
- Near Silverback (the holographic gorilla) is a cop car that gives you the "Save Kinetic" quest when you click on it (or you can just go to the area that Kinetic is in and pick up the quest by being in the area)
- You get a perk for doing all of the missions in the tutorial, including the semi-hidden ones
