Zombie apocalypse game that takes place mid-outbreak, where you have to work with friends to find an escape. You play through different scenarios (stuck in the middle of the city, trapped in a hospital, barricaded in a mall, etc) with different methods of escaping based on what you find while working with others. Maybe you can find keys to a military truck, but have to fight through a horde down in the parking garage. Maybe you find a way to radio an escape helicopter, but you have to gather a certain amount of valuables for the pilot to believe it's worth risking. Maybe you get enough weapons together to outright fight through to the city's outskirts.

Gameplay would be detailed scavenging, building up your character, and fighting off zombies. Over time the environment would change, making for more mutated undead variants, issues like the power going off or rogue military sweeping through, or an outright storm kicking up that would make it hard to hear zombies or navigate the streets. The environments would be made with multiple ways to get through them (vents, keys to be found, breakable doors).

I basically just want an ideal, perfect version of RE Outbreak honestly. I always loved that game in concept, but actually playing it was a mess.
