My last artifact is a project that I started in GAM 415, it is a paintball game that has a time limit and the object of the game is to the highest score possible within that time limit.  There is no real win or lose condition just a game to have a little fun with.  However, the twist of this game is that you have to do this with almost no gravity.  For this course I did have to almost completely rewrite the code for the game because the original was created in a much older version of Unreal and there were lots of unnecessary assets in that project.  The hardest thing to accomplish with this project was to get the target spawneer I created to spawn different types of targets without some of them losing their collision settings or just plain not spawning in right.  I got a few of those bugs worked out but it is still very much a work in progress.
