The idea is that you can leave one map and go to another, but all your progress from the old map stays. You can then travel between maps freely, bringing supplies and survivors with you as you please. Provided you have the necessary resources to travel there.
Currently, the game is, imo, lacking great end game content. This would provide a good way to raise longevity in play sessions, as well as difficulty. Players will have a good reason to thoroughly clear out a map, or come back to it if things get too tough in the next map. Not to mention stay on good terms with friendly Enclaves. It all adds up.
Start any map and it plays out like normal. You have a mix of regular and blood plague zombies (BPZ) and a good amount of loot. But as you progress to the next map, bringing a max of 10 survivors with you (assuming you have 12, 2 need to stay behind to hold down the fort) in two trucks packed to the brim with supplies. The amount of survivors, supplies, and resources like gas and ammo it takes depends directly on the amount you try to bring with you. So taking less makes the trip cheaper.
- Once in the new map, things take a turn for the worse. First off, that default home base is not available, so you have to come ready to take over a bigger base, or rough it at the edge of town. (optional, but highly recommended)
- Secondly, the amount of plague zombies increases. If the ratio is, say, 1:3 in the first map, it's not 1:1 (aka, 50%) of the zombies. In the third, and final map, it'll be 100% of the zombies.
- Lastly, the loot should be better. Not necessarily in more abundance, but definitely better quality. I would even go so far as to lock some of the best items in the game behind being in the 2nd or 3rd map. This will not only encourage people to go and push themselves to getting to the harder parts, but it will encourage trading, teamwork, and preparation. Plus, it gives people a reason to go there if they're having difficulties in the earlier maps. You might scout the later maps and burgle some HQ weapons away in the dead of night.
Of course, you could always just have the maps function completely normal, but by utilizing the above tweaks, you provide a much needed end-game expansion that the fans would love. Complain about, sure, but love.
Regardless of whether I have your votes or not, thanks for reading through.
