The stunning console-quality 3D shooter Implosion is being offered FREE by IGN. It currently retails at $9.99 (£7.99 for Brits).
Using your iPad or iPhone just visit the link below and click the Get Free Game button, then tap on the code. This will open the App Store with the code filled-in, and you can tap the Redeem button at the top right to start the download.
No tricks. No gotchas. Just plain old generosity, it seems.
EDIT: If you get any error messages along the lines of the code not being redeemable, or the offer not being available in your country, keep trying by refreshing the page at IGN. Apparently the offer is proving very popular…
