Are any of the games online multiplayer?
No — all games in Skywar are single-player against AI. Zone Rush has multiplayer-style squad rotation but you fight against the computer.
Why does each game look different?
Each title is its own hand-tuned project with its own physics, AI, audio and progression. They share a portal (the site you are on) but they are not templated from a common engine. War Room is a strategic strike sim. Fighter Ops is a 2D dogfight sandbox. Vault Raid is a stealth heist. They feel different on purpose.
Are the named airframes, ships and missiles real?
Some names are inspired by real-world designations (F-16, Spitfire, AH-64 Apache, Tomahawk, ICBM). All performance values, behaviors, scenarios and damage models are tuned for arcade play, not simulation. None of the content represents real militaries, governments or programs.
Is there a story or campaign?
War Room and Missile Command both have a mission progression. Other titles (Sky Battle, Swarm Arena, Vault Raid, Zone Rush) are session-based — pick up, play, score, leave.
