Spend quarantine fighting the undead in this brower-based game that's been around since 2005. 

www.urbandead.com



You get 50 action points (AP) to build barricades, find supplies, and ofcourse fight zombies. AP increases every half-hour so you can drop in a couple times a day.



I've been playing on/off since 2006 with some multi-year hiatuses in between. It's a lot of fun and easy to play with the time constraints that come with adulthood. 



If you guys want we could create a Retro-Daze survivor group lol
