Sylvester in Space is a computer game created by Kevin Karstens in 2001 as a promotion for Cracked.com.
The game stars Sylvester P. Smythe and is a simple side-scrolling shooter, featuring Sylvester taking on asteroids and what looks like a Borg ship.
While most of the artwork is by Karstens, the "life meter" features an illustration of Sylvester that appears to be by John Severin.
