Deadlock. Next Valve game. Previously known as Neon Prime, Citadel. Competitive third person hero-based shooter. 6 vs 6 battling on huge map with 4 lanes. Usable abilities and items. Tower defense mechanics. Fantasy setting mixed with steampunk. Magicians, weird creatures and robots. Fast travel using floating rails, similar to Bioshock Infinite.
Basically, fast-paced interesting ADHD gameplay. Combination of Dota 2, Team Fortress 2, Overwatch, Valorant, Smite, Orcs Must Die.
Hero design pretty much inspired by Dota universe. Main map references modern steampunk European city (little bit like Half-Life). Initially game had sci-fi elements inspired by Half-Life and Portal, but after bad feedback dev team decided to focus on fantasy.
What I’m saying is that zombie games, open world, and battle royals were big trends but class-based shooters have always been around. The uptick in titles after overwatch’s success happened for sure, but they were still too few and far between to really be a trend
