At long last, the annual Anniversary Bash is happening to celebrate 21 years since the shareware release of Jazz Jackrabbit 2! Beginning on the 6th of April, 15:00 GMT+1, it’ll run for 4 days.
For those unfamiliar, this is a public casual online event that hosts a hand-picked set of maps in the Battle and Capture the Flag gamemodes. You can even just chat if you’d like—you might spot a retired veteran! More information is available in this forum thread.
