This is the map Favela from Modern Warfare 2 remade in Minecraft. I finished it with a friend within 24 hours of starting.
We tried to make it as much as possible like the actual map. We walked around on actual Favela while comparing it to minecraft sizes continuously, to try and get the sizes and materials as perfect as possible. Due to this, the insides of buildings are a bit cramped due to the 2m thick walls instead of 10cm. Apart from that, everything should be almost exactly as in the actual game. One thing I'm particularly happy about is that because of this, all the jumps that are possible in MW2 are also possible in Minecraft.
