Beer goggles Achievement
Used all three switches, defeated the two phasers, and chased after Vertigo within 60 seconds
This is on the "Taking a Chance" stage. Vertigo will be affecting you with her powers making it a little hard to see, but there will be 2 switches you need to hit to power up the main switch. You can follow 2 power lines to get to them. 2 enemies will spawn while you're doing this, so take them out, hit the third switch, and proceed and it'll pop. There is a checkpoint at the same spot where this achievement pops, so make sure you feel confident that you'll get it, otherwise you'll hit the checkpoint and have to restart the chapter.
