Ascend is what happens when a small team plays Titanfall, likes what they see then decide to go and (try) make something better.
It's a sci-fi multiplayer shooter, you can run on the walls and you can call down a mech (well, an exo-suit here) to climb into and really wreck some shit. So far so Titanfall.
The difference here is that there's a lot more attention being paid to the on-foot parkour stuff, with not just wall-running present but all kinds of additional tools and combos available, like a hook which lets you swing around like a gun-toting Spider-Man.
What's there looks cool! What's there isn't that much right now, though, with the game having a projected release of 2018, and only having just turned up on Steam's Greenlight.
