The survivors have to collect keys to power a time machine that will let them escape and the raider wants to kill them all. The raider can destroy the time machine so they are forced to use a shittier time machine as a last resort. Survivors can use items and abilities to hide, travel quickly, or slow down the raider, and can temporarily transform into fighters from the show. If enough of them work together to attack the raider they can actually kill it too, I believe.

There have been closed beta tests where players were allowed to record gameplay, so you can find videos on youtube of full matches.
