I made a script mod that forces the Legendary threat level at any time before Wave 1 activates.

Please update ur mod!

is it SFO compatible?

@warsonger I loaded the mod and started a new Head to head which spawned 4 armies.

It's certainly weird, have you applied the mod before starting the campaign or while it has been already started?

@Vacloud

since my last post, i did extensive tests with 3 friends, all campaigns worked perfectly and spawned legendary invasion at both invasions times !

i had same bug as you in the 2 first tries, then it worked constantly in every new campaigns, i dont have any explanations to it, but at least it works

Mod doesn't work. Playing Head to Head. Chaos spawned 4 armies. What a god damn shame.

im in MP versus campaign with a friend: turn 99 first invasion got 4 armies, is legendary only for the latest ? or does teh mod needs a new game (instead of what is stated) ?

and it works also for coop? Because we are next to 100 turns and we have a first invasion of only 4 Armies. Shouldn't they have something like 10 armies or more?

New invasion, from the latest patch.

numbers of spawn armies are the same of old version or of new's chaos invasion?

Thank you for making this! Would it be easy for you to make similar mods for the other chaos difficulties?

Thanks for the feedback!

12 stacks of Chaos by turn 100, mod works great in co-op. Thanks a lot.

I guess yes, if the invasion haven't started yet

is it save game compatible?

Version error from files is a common error with the workshop, not exactly the mods fault. Try resubscribing, turnin off and on your mods.

Feedback: I'm afraid to tell you It doesn't seem to be compatible with multiplayer, at all. My buddy and I tried it with only this mod and I still get the error message about the different files.
