How To Play Ben 10 Alien Force: Forever Defense Post Flash-pocalypse.

With the game no longer being supported on Cartoon Network after the Dec 31, 2020 end of support for Flash, the best way I found to still be able to play the game is by using BlueMaxima's Flashpoint ( https://bluemaxima.org/flashpoint/ ), a webgame preservation project. There is a manual available but the TL;DR is simply, download the installer, launch, search "Ben 10: Alien Force - Forever Defense" and hit play. This is a perfectly acceptable version of the game to speedrun as it is simply a "port" directly from Cartoon Network itself. Use at your own risk.
