Never. You are meant to be overran at the end. I do not know how easy it has gotten with one wave removed. I have been given no feedback if things have gotten better for "lesser" computers.
I have moved on from this project.

When do the waves end at the last base?

I have removed one wave from each side. I do not have a "lesser" computer, but your feedback would be nice as I've never been given enough info on what people can and can't handle. This map I made with very small amount of controlled waves unlike my other maps I've made.

Needs to be majorly toned down for those with lesser computers or something else to trigger the win/loss conditions got to plasma bugs then crashed not sure if it was the game or my computer but there was a struggle none the less.

i cant finish this map so hard :/

You are to be overran. But it seems I seemed to use the wrong disable feature. I disabled transportation and not reinforces for when the plasma bug notification pops up. This was one of my last things I added before uploading.

What's the win condition in this? Do you just hold until the waves just swarm over you or what?
