I've been ruining some of my planes recently to make them seem like they've been through and apocalypse. So far, it's been really successful.

Lore:
In an alternate 2015, a Wright scientist finally perfected his cure to dementia. Or so he thought. His test patients showed a full recovery, but they started to mutate and infect others. Wright was completely overrun with zombies within 3 days, and Krakabloa fell after 2 years of endless fighting with the infected. Maywar had time to evacuate their entire population, and so a band of survivors live on the Maywar mainland. Snowstone never had a chance to launch The Snowstone Incident, so they have been able to survive the outbreak rather well. The outside world has ordered a quarantine on the archipelago, but is still researching efforts to cure the poor inhabitants. The remaining Krakabloan Militia fighters strive to maintain order in a world overwhelmed with this horrible plague.

Painbringer: heavy gunship.
The Last Resort: fighter.
Yeti: attack plane.
Scarface: attack plane.
