Are there any MOBA games that are DRM-free and playable over LAN? Bonus points if:
- they have PvE (players vs bots)
- they have an offline mode vs bots
I'm fine with it being either a PC or Android game, as long as it's DRM-free and LAN-capable.

The only one I can think of is the Warcraft 3 version of Dota.

And yes, I understand the irony of trying to find a MOBA without an "O".
