Origin Mass Effect Trilogy $12, Torchlight and Slender for $2, Awesomenauts $3.74

PSA: There are some pretty good online sales today and here's a quick roundup of some of the best including 80% of a variety of games at GOG.com, Awesomenauts and all DLC 66% off on Steam and the much loved Mass Effect trilogy only $12 over at GMG for Americans.

The Mass Effect deal comes as part of a broader selection of game franchise packs on GMG this week, including critical darling The Walking Dead at 50% off, all of which can be reduced again by 20% using the voucher code GMG20-8MUTY-M21VN.

Keep in mind if you're interested in the Mass Effect deal however, that the PC versions don't support gamepads easily, come without any of the big DLCs for Mass Effect 2 and 3 and are only redeemable on Origin, if that bothers you.

Over on Indie Game Stand the game of the day is Northmark, an indie RPG crossed with a Magic the Gathering Esque card game I'd not heard of until now but looks pretty cool. That's a pay what you want deal too if you don't feel their suggested price of $10 is reasonable.

Steam are also holding a short sale on the AC-130 Warthog module for Digital Combat Simulator, so if you fancy crashing a plane, you can now partake in your very specific hobby for 70% less.

Lastly, since Amnesia: A Machine for Pigs unlocks in about 5 hours, it's just about your last chance to get that game at 20% off the standard price of $20. There are plenty of reviews in our roundup here to help you decide how much you want to scream tonight.
