I may not be using the right terminology. What about Mods for the vanilla maps. I know there is QWTA, Dusk, Brace, etc. These mods also work with custom maps.
What I’m suggesting is a mod that add or subtracts deployable locations, add or subtract vehicles, obstacles. There is old footage of ETQW when it was in progress and the explosions were amazing. The explosion would begin with the “dome” and expand outward and you could see the pressure waves rippling on the ground.
Additional things like MG bunkers that an engineer can construct. How about Hyper bunkers for the Strogg on their defense maps? This could fix things like on Area 22 there is a MG on the side of the GDF base facing the hill. MG should’ve been placed in the building facing the last Strogg spawn.
These are things that could be added to QWTA instead of creating another mod. Just deactivate what you don’t want.
