Looking to play with friend against NPC/AIs (ie: PvE)

[NeilF]

I'm looking for a flight sim to allow a group of us (upto 6) play against AI/NPC opponents, ideally in different missions/settings.

IL2 seems to come up as allowing us to do this...?


So can someone help me out and let me know:-
- Which version of IL2 would allow us to do this?
- What would we need to do this? Would I need to download and run a server for example for us all to play on?

Any other advice/insight would be appreciated!

Thanks!
