One of the first and most important things you have to do in Corridor Z is familiarize yourself with the different colors of light you’ll be seeing. Green lights mean you should get ready for a turn. Gold lights signify rations, and red lights tell you that there’s a weapon you can collect. Lastly, hit down when you see a purple light, as that’ll lead you to a diary page.
You’ll also have to throw some obstacles at the zombies, but that won’t really do much except stun them or have them reeling backwards a little bit, even if you’re throwing something comparatively large.
There are a few ways to get yourself some additional rations without having to spend a dime of your money. Go to the app purchase store and you’ll have two options, starting with the choice to watch advertisement videos. It’s mostly a quick and painless process, so don’t hesitate to watch an ad in exchange for free rations. You can also complete offers available on the app purchase store as an alternative. Lastly, you can simply go through each stage to collect rations, though this is obviously the hardest way to go.
You can intentionally kill off your character once you’ve passed a mission, then go on the next. Running for too long would make it much harder to complete all your objectives, though the reward there would be additional rations. In fact, you can run for as long as you could if you’ve already gotten things down to a T – that would mean having impeccable timing when gathering weapons, making turns, and dealing with obstacles.
Yes, there are still a few bugs in Corridor Z, including the tutorial instruction that appears when you pass to the next room. This would greatly slow down the transition and can be very irritating to deal with, but there is a workaround here that won’t tamper with your progress. Quit the game and restart it again, and you’ll be back in the same point you were, as if nothing had happened earlier.
