Don'ts:
- Easily getting spawn trapped like in Ghosts
- Tiny maps that only have 1 or 2 height differences
- Easy camping spots that are overpowered
- Completely linear maps
Do's:
- More height differences with plenty of ways up
- Different weather, affecting movement, aiming, and sight
- For Ghosts: make a space map, it was a large part of the story, so make an online map for it.
- Night time maps or maps where time changes
- BIG dynamic map changes that remake the whole map, one of the things battlefield has over COD
- Less linear maps
- Something totally new that COD hasn't done
