Humble Bundle: Deep Silver below average giveaway

The key includes the games Metro 2033, Risen and Sacred Citadel.

Key:
PQW2T-ZCHN5-FIPZ█

I have taken away the last character from each part of the key, Should be fairly simple to crack, but if people find it too hard to crack, I shall reveal 1 character at a time.

WARNING: You will not receive gift copies of any of the 3 games if you already own them

If you do happen to crack it, post the key in the comments to prove it.
