A Christmas Gift video - Project Valkyrie mod for Half-Life 2

Project Valkyrie is a multiplayer first person shooter developed for the Source Engine. Players suit up in the Valkyrie suit, equipped with a powerful arm cannon integrated into the suit and the ability to morph into a sphere for faster mobility and different attack capabilities. Previously titled Three Month Mod, it was thus named for the amount of time it had taken us on the project. Three months from conception to release. Everything was done simultaneously, from pre-production concepts, to code, to mapping. Unfortunately, due to a delay with the public release of the Orange Box SDK (we couldn't release without it, even though we were already Orange Box!) our initial release had been delayed.
