Not yet, I haven't prioritised modifying the missions that focused on small unit composition, rather than using Radio Posts. I will get around to editing those missions soon, with the intent to make them more difficult and mix up that starting units.

Are the first two levels available?

fair i mean my pc is brand new so this is abit odd also i use external this is why im not shocked at crashes

I'm suspect it would be the 'cheats' causing the infinite spawns from the Bug Hives. I do not have this issue when playing the mission.

The lag may be due to a combination of the edited mission and the 'cheats'. This mission I increased the attack waves towards the central base. The extra bugs over time would cause some lag, but you usually don't experience this till 1hr30 - 1hr50 mark. If you are using console commands to spawn additional units or give additional supply, this would speed up the lag onset.

note some of these maps didint work probly or they just where buggy

idk if its because of my cheats i use to play but most maps did work when default and even when i use my own custom map these maps id have to throw a coin and randomly toss and see if the map would break

2 things would happen

1.overspawning

the first map i played was 3
this one while it did work it wouldint slow down on bug spawns

aka the one im talking about is the mines and clearing them

it was so bad that my pc was going so slow my units couldint hear my orders

idk if this is a broken map or my cheats as stated but id maybe suggest looking at that map and seeing if that happens for you

as it was really bad even with the earthshatter morters and me trying to cap the enemy spawns off with god mode they would not give up even with instant kills i could bearly get frames back to have them go poof shortly after

Yes, these change the settings in the mission to allow you to use the extra units in SICON. The original campaign missions will be restricted to the handful of units that the mission was originally designed for. (in Peace of Mines case, Engineers and Radio Operators only.)

question if i have the mod do i need these missions
