The Steam Summer Sale isn't the only deal in town for PC gamers. Green Man Gaming is also running a sale, and if you enter promo code JUNE20 at checkout, you'll get an extra 20% off most of the already-discounted games. That amounts to some serious savings on lots of worthy games. You can find the full list of games on sale here, or read on for the highlights.

That extra 20% off bumps many of these deals in to best-ever territory. PUBG, for instance, normally sells for $30, but it's on sale for $20. Take 20% off of that, and you're looking at a final price of $16. Not bad at all. Cuphead has a similar thing going on, landing it at $13.
