Frutiger Aero OS

Players place the Aero Computer block and power it, then use a desktop with a Start Menu, taskbar, live clock, a multi-line Notepad editor and a Music Player that plays 10 unique CD tracks. Further apps cover a Gallery for a postcard collection, Personalization for wallpapers and icon sets, a Shop that sells items for in-game currency, and an Arcade with doodle jump, flappy bird, tetris and snake, where prizes include iron, gold and diamonds. An Internet app holds 3 bundled websites, including a wiki, a map and the AeroOS.corp site. Network features depend on a router, and printing depends on a printer.

Collectibles are part of the progression. The mod adds 11 CD discs and 10 postcards with unique artwork. A broken computer variant shows a Windows-style BSOD screen and can be repaired by inserting 5 components. Four structures, including the Aero Pavilion, Aero Greenhouse, Technozen Station and Tech Shop, spawn naturally in green biomes.

The mod runs on Forge for game versions 1.20.1 – 1.20.6, with files for six release versions. Both the server and every player need it, so the environment is client and server. It is released under All rights reserved and is not open source. The latest file is 0.22.0 for 1.20.6, published on 2026-08-31.
