Factory Under Pressure

A solo mashup connecting your real Factorio factory to real Combine battles in Half-Life 2. Both owned games run together; switch windows with Alt+Tab.

Start from scratch on Nauvis: mine resources, build furnaces, and grow your factory. Producing 20 iron plates, 40 copper plates, and 30 iron gear wheels triggers three Combine squads. Furnaces, drills, assemblers, and labs stop during each lockdown. Defeat the squad in an original Half-Life 2 arena to restore production. After the third encounter, keep building freely.

Requires Windows, installed Factorio 2.0.77 or a compatible 2.0 version, and Half-Life 2. No Space Age DLC or third-party loader required. Single player, one arena, three squads. Melty launches both games; saves and runtime data use an isolated profile.

Version 0.1.1 passed Melty's two three-minute installed-release tests. Automated checks verified both game connections, actual manufacturing, three real NPC death counters, and machine lockdown/restoration. Test mode accelerates manufacturing and applies scripted damage; this is integration testing, not a full manual campaign playthrough. Melty's generic code-loaded detector cannot inspect this custom launcher layout. Gameplay screenshots show actual game windows from testing.

Original mod code and arena geometry: MIT, remixes allowed. Published by this Melty creator account, built with Codex assistance and rehan-remade's universal-modder workflow. Factorio and its content belong to Wube Software; Half-Life 2 and its content belong to Valve. Retail assets load only from players' own installations and are not redistributed.
