Alexander "Alex" Roycewicz was the former level designer for Infinity Ward that designed many maps for Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2. He has worked with Infinity Ward since Spring, 2006 and eventually quit July 2010.
Roycewicz joined the Infinity Ward team back in May, 2006 when Call of Duty 4: Modern Warfare was in development. He eventually became a level designer and designed multiple maps for Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2. Multiple easter eggs can be found on maps he designed; which included his name and the year the map was designed. Roycewicz's daughter, at the age of six, eventually died of cancer during the development of Call of Duty 4: Modern Warfare, and the last thing she held was a teddy bear. That's when Infinity Ward and Roycewicz made an agreement to start placing teddy bears to multiple maps and levels; to honor her. During the development of Call of Duty: Modern Warfare 2 in June, 2010, Roycewicz left Infinity Ward following the 2010 departing of multiple Infinity Ward employees. He eventually took up an offer to join Respawn Entertainment as a level designer, following 45 other employees.
