It's that time of the month again, when Pocket Gamer gives away a bounty of codes for last month's absolute best games to our wonderful community, the App Army.

For those unaware, that's our diehard band of mobile gaming enthusiasts. In exchange for their critical thoughts, we give them codes for unreleased games on a weekly basis and you can join in the fun by simply signing up on Facebook.

That's a requirement to get a chance at a code in the giveaway, but more on that later. Let's kick things off.

Opus: Rocket of Whispers

Opus: Rocket of Whispers is an emotional, story driven adventure set in a post apocalyptic winter.

You play as two different survivors, who are trying to build a rocket so they can give the deceased a cosmic burial.

At review, we gave it a Gold Award and described it as "A deep and moving adventure that you should pick up and play this second".

Okay, I'll give it a go

Not so fast! First you have to sign up to the App Army here, then fill in the super quick Google Form below. If you can't see the form, this link should take you to it.

And that's it. We'll be back tomorrow with a brand new game so keep checking back at 5PM BST.
