Chromehounds

is a 2006 mech simulator video game developed by FromSoftware and published by Sega for the Xbox 360. The game is set in an alternate universe where mecha known as HOUNDs battle for control of Neroimus, a fictional region near the Black Sea. Chromehounds features a system for personalized customization of the player's mecha and an online campaign mode where players wage war in a persistent world over Xbox Live. The game's online servers were shut down in January 2010. The game's online server functionality was partly restored in May 2025 using Xenia Canary emulation.

==Gameplay== Chromehounds is a mech combat simulation game where the player controls customizable mechs, called HOUNDs, from a third-person perspective. The game offers opportunities for strategic thinking, as there are sometime multiple objectives for each mission. Both the single player and online game modes occupy different points in the game's timeline: the Single Player "Offline" story mode chronicles events just prior to the outbreak of the Neroimus War, the game's central conflict, while the Xbox Live "Online" mode takes place during the actual war.
