Valve level designer returns to Twitter after lengthy absence to reveal he used a pot to add handles to an electrical box in Counter-Strike

Magnar Jenssen is a level designer with serious pedigree, starting his career at Grin before stints at Starbreeze, Avalanche, and then from 2013 onwards working for Valve. This was an auspicious year for Counter Strike: Global Offensive, with the Winter Offensive update in December 2013 adding two new maps to the game, Cobblestone and Overpass.

Both maps have become fan favourites, although in Overpass’ case it took a fair amount of tweaking, and one of Jenssen’s first tasks at Valve was to work on Overpass details. Jenssen doesn’t seem like much of a social media type, but for the first time in around 18 months he returned to Twitter to share a development deep dive on an element of the map’s design.
