There’s a major new Arma 3 expansion launching next Monday, April 29th, bringing the military sim back to its Cold War roots. Impressively large as it looks, Global Mobilization isn’t by Bohemia Interactive, but the first release from their “Creator DLC” commercial mod program and produced by small team Vertexmacht. Mods going commercial isn’t a new concept, but it has backfired for a few studios, including Valve’s own failure to get the idea off the ground with Skyrim, and Blizzard’s swiftly-abandoned premium mods for StarCraft 2. Still, Bohemia’s approach seems more structured, at least so far.
