Kosire

Rasmus “Kosire” Geil (born on August 11, 1994) is most known for his contributions to ‘Counter-Strike: Source’, a first-person shooter game developed by Valve Software. His interests are pretty much just level designing. Rasmus has design experience with all Source Engine games (A engine developed by Valve Software), from the original ‘Counter-Strike’, through ‘Half-Life 2′, ‘Counter-Strike: Source’, ‘Day of Defeat: Source’, and ‘Half-Life: Episode Two’. His first amateur work - a simple hostage rescue map for Counter-Strike: Source with ideas from a old picture on google which no more can be found - was released in 2006 (when he was 12), bringing him directly into the amazing game design world. His newest work is a map for the very known Counter-Strike league ’CAL’. In 2008, Rasmus got a job from Cal league which was his first actual job for making maps for Source Engine.
