Alright, first off, this map is awesome.
But lets get to the point.

Could you possibly consider a map like this, only with UFOS and ALIENS?
And yes, it would be fine to have CS:S or not.

Setting: You're inside a farmhouse, with one room that has security monitors. There's a barn and a wheat field. There is also multiple landmarks and other places hidden nearby.

Mechanics: You have a radiation meter. And working cameras set around the farm.

Events: Here's where it gets fun.

UFOS: For UFOS, you could maybe take small balls of light of different colors that blink, pulsate, or stay solid in the sky. They can go at warp speed or slowly hover. They could also be sighted near the ground, near a forest or something. And occasionally, a disk shaped, V shaped, or a wisp of light would sometimes appear in the sky, and hover for a few seconds or fly across the sky. They could also cause interference with electronic equipment.

Aliens: Aliens work kinda like ghosts. Except, they could patrol the farm, hide in the barn, run through the forest, or even enter the farmhouse, and stare through doorways and windows. They would look like normal aliens, or stalkers. Or even charples.

Other Occurances:

Sometimes, a blinding flash of light would burst for a small second, and then disappear.

Other times, a loud boom could be heard from far away, or sometimes right at the farmhouse.

From time to time, a bright light could also shine through every window in the house, yet with no source.

Well, that's all the ideas I for now.
This probably won't happen, but if it is possible, let me know.

Thank you
