hosted a 48-hour Full Indie game jam at the Centre for Digital Media in Vancouver, B. C., Canada. While at this jam, he teamed up with designer and artist Cody Church
and musician Brian Werst
to create Metal Spawn
. The idea was it was to be a cross between Space Invaders
and a tower defense game
. Of course, forty-eight hours is a short time to make a game, coupled with being the host, so not every feature that was planned was implemented. The theme of the game jam was "spawning" as it was the Father's Day weekend in Canada. After the jam, Mr. Birkett went back and made some minor tweaks as well as adding animation to the aliens, as Mr. Church had made the animation art.
