World War 3 will be coming exclusively to Steam Early Access in 2018. WW3 features large-scale combined arms combat in Warzone mode, complete with vehicles and high-tech drones. Depending on the game mode there’s also going to be an emphasis on attack or defense, a little like Siege.
There’s also a battle royale game type known as Recon. It’s fairly different than the usual formula though and focuses on small reconnaissance squads tasked with capturing high-value military targets.
Combat promises to err on the realistic site, despite World War 3’s announcement trailer demonstrating some obvious bombast. Full ballistics physics will be at play, while the maps themselves will be set in real-world cities like Moscow, Berlin, and Warsaw.
