Following the universal acclaim of last week's "Cooperative Polygraphy," NBC stalwart 'Community' will again brace for a big episode as Donald Glover says his goodbyes in "Geothermal Escapism." The first photos of the post-apocalyptic concept episode has arrived, along with a first look at 'Castle' star Nathan Fillion as a mysterious janitor in the weeks to come!

You're warned of the most recent 'Community' spoilers from here on out, so while we know that Pierce's dying wish sends Troy off on a worldwide adventure, Abed certainly won't let his best friend go without one last crazy Greendale activity. It's no paintball, but the full photos of "Geothermal Escapism" see the student body once again taking an ordinary game to an extreme, donning 'Mad Max' attire as everyone pretends the floor to be lava!

And while Donald Glover's departure (no word on season 6, just yet) will prove hard to swallow, the next week's episode "Analysis of Cork-Based Networking" will see a cavalcade of guest stars from the likes of 'Firefly' vet Nathan Fillion, to a returning Brie Larson and 'Terminator' star Robert Patrick.

The latest news from the TCA has us brimming with optimism 'Community' will live for 6 seasons and a movie after all, but in the meantime, check out Nathan Fillion and more in the photos above and below, giving us your take in the comments!
