Swear theirs a tech demo that came out a couple? Years ago. Environment looks very similar along with the projectiles and the way they look.
I was trying to think if this was something we had seen teased before too. Nexon has a TON of these "Project Blahblah" games in the works...
PROJECT D (maybe what you're thinking? it's like a fast-paced Division/MGO online shooter by Nexon GT)
PROJECT HP (kind of a fantasy/magic For Honor?)
PROJECT ER (different knight&bowcaster fantasy MMO)
PROJECT MAGNUM (side-scrolling'ish brawler RPG)
PROJECT OVERKILL (co-op celshaded MMO, supposed to be like Dungeon&Fighter in 3D)
PROJECT BBQ (traditional'ish PSO multiplayer RPG in a fantasy world)
PROJECT MOD (MapleStory Maker, basically)
PROJECT DX (
cellphone RPG set in the world of Durango Wild Lands?)
PROJECT SF2 (cartoony RPG for mobile)
PROJECT P2 (?, for PC and consoles, described as team-based, fast-action, stylish character action, maybe Arc?)
PROJECT P3 (? Multiplayer fantasy MMO with "dark and dangerous" dungeons)
PROJECT DR (?)
...Specifically regarding "Project Embark", I'm not sure if we ever saw much of Arc Raiders? Nexon did announce the acquisition of Embark with the teaser image below, and you could catch maybe some
sneakpeaks of art/landscapes snuck into their phptogrammetry tour (that's mostly drone footage, not real engine tests, but you can see some of the biomes that they did make in their Vimeo archive.) Don't recall anything beyond that, but as is clear here, keeping up with Nexon's Project Projects is a real project.
