Shmup Slam 7 Announcement Trailer! May 17th and 18th. Shmup Slam has returned! To those new to the event, Shmup Slam is a GDQ-ish type of event that I do that hosts a non-stop wave of live shmup runs where players set their own scoring or survival goals and try to pull them off live on stream. What’s really fun about shmups, unlike most speedrunning, is that if the player messes up, the consequence is destruction and a game over, vs just losing some time or a PB. So the stakes are extremely high which makes watching and playing the genre in this setting very exciting.

This year Slam 7 is going to be hosted at Akihabara Arcade in Westminster, Colorado, which will be extremely cool because if you are a fan of the genre but don’t feel like your wanting to play a live demonstration on stream, coming to the event to hang out and watch and play all the awesome arcade cabs at the venue is still going to be a great time :-)
