Looking for a type map/mod but don't know what to call it

[TheButcher55]

Is there any mods out there which would basically be the opposite to survival? Like a map where you have to break through massive enemy defenses and destroy a particular protected structure.

Try survival run. There are more versions, its basically an escort mission combined with survival and you have to bases and defenses on the way.

The campaign missions can be like that.

Here is an explanation of how to play campaign missions in FAF: viewtopic.php?f=2&t=18413

Try "DDDX_RPG_survival", but as player 7
You will play alone, allied to the attacking swarm, your mission to make life miserable for the defending team and help the swarms break through the defences. This can be done either by sniping out ACUs, extra push on the flank that is failing (for example, navy), or simply denying the defenders access to killing Gateways (they spawn extra units if not killed).

I know it's not exactly the coop you had hoped for...but if you have a good enemy team that can hold out against the attacking swarm, it can be really dynamic and challenging
