Innovative touchscreen blaster Midnight Star finally came out this week, and whadya know, it's pretty good. We called it "a fast-paced and engaging tappy shooter that looks stunning".

But you will need to grind for currency inside this free to play game, to get the best weapons and upgrades. Or, buy some with in-app purchases.

Or, you can check out the free comic book companion, Midnight Rises. Reading the comic, and completing a few chores, will unlock currency inside the main game. And to help you do it fast, we've put together a complete guide.

Once you have unlocked a bonus in the comic, just log into your account and then load up the main game. Find your profile, and choose "Midnight Rises" from the achievements panel. Then, just tap the icon to grab your goodies.
