Remix: War Tactics

Build a small, playable browser game inspired by "War Tactics" (Strategy).
Concept: A turn-based tactics game, 18 unit types, 12 maps, 8 COs with signature powers, full 10-mission campaign, online multiplayer, hot-seat, map editor, and a war-room stats hub, all playable instantly in the browser.
Tone/hook (from the game's own page): Build and use units to defeat your opponent. Play online or against the cpu!.
Tech: use React; keep it to a single page that loads instantly with no login or install.
Controls: touch controls (tap/drag) that work on a phone plus keyboard and mouse on desktop, shown on a short how-to-play screen.
Multiplayer: the original is listed as multiplayer. Start with a local or bot opponent, then add online play (e.g. WebSockets) once the core loop is fun.
Core loop: include progress saved in localStorage.
Steps: 1) get the core mechanic playable with placeholder shapes, 2) add win/lose conditions and restart, 3) polish feel, visuals and sound, 4) add your own twist (setting, character or one new rule).
Make it your own: don't copy the original's name, art, text or code.
