While its logo might be eerily similar to the Blizzard's monolithic shooter, Overload is a different beast entirely. Whereas Overwatch is mostly a classic FPS game with a couple of twists, Overload is actually a six-degree-of-freedom shooter from the makers of the original Descent. What this means in gameplay terms is that your little spacecraft can rotate and spin in any direction you want it to!
Since trying to explain this concept through words alone is a bit difficult, allow me to share with you the recently posted launch trailer. It will give you a good idea of what six-degree-of-freedom movement really means, and most importantly, what Overload is all about. Have a look:
If you were hoping for a fully finished game I'm afraid I will have to dash those hopes as Overload has just recently landed on Steam Early Access. The current version features 4 unique "Challenge Mode" levels, two gameplay variants that change the focus to survival or efficiency, as well as a sample singleplayer level that showcases what the main campaign will be all about. In terms of weaponry you have 13 different tools to mess around with (7 primary weapons and 5 missiles), as well as 10 types of robotic enemies to absolutely annihilate with said weaponry.
To learn more about Overload and what exactly the developers plan to do in Early Access I would recommend you head over to either Steam or the official website. On the other hand, if you would like to give it a try for yourself you can find the playable teaser by going over here. As a final note, here's a couple of images of Overload in action:
