This cool £11.87 download deal saves you a mighty £16 over the retail version. Worried about hard-drive space? Come on now, we know the disc has a massive install anyway. Use the site's Facebook discount code to chip a little more from the price.
The Xbox One version of the game has been less buggy than the PS4 release and many issues have been patched. If you've come this far with the series, we know you'll want to try this at some point. There's no patching the stale ideas and arsehole AI though. To be honest, I'd recommend Rogue over Unity any day of the week. This is a great price though.
