Bot / Big Battle Mods?

[timski]

Is there any mods to add more bots or play a mode like XL from SWBFII?

I'm not aware of any for BF1, but BF2 has a big modpack that adds back all the BF1 maps and adds extra custom maps, KotOR era for Instant Action and Galactic Conquest, and many extra modes. One of the modes is a "BF1 Mode" that matches BF1's feel as close as possible (sprinting is removed, classes have their BF1 weapons, etc). The only thing you can't do is go prone (you can in the genuine BF1).

There's only mod maps as far as I know with huge numbers. Helms deep is one with a lot of AI.
If you use a dedicated server for online you can also tweak the numbers.
