The only difference I see from MP3 is the hanged skeletons.

EDIT: And even those are from MP3.

you serious? Almost every background and every bunker piece is from MP3.

find in MP3 Scenery

Needs more ORIGINAL stuff. Make your own spaceships instead of ripping off Gotcha's.

Gotcha released a very large amount of individual pieces, ranging from tiny bunker chunks, to blast doors and full bunker pieces. Nothing was ripped off, Jangrik had to think up and assemble the ships himself. He just used a pack of bits and pieces that Gotcha made.

It's like saying this guy is ripping off Lego because he uses their bricks.

True, but in Map Pack 3 there are a few maps that look almost exactly like this one. Just sayin.

EDIT: Oh. Didn't notice some of the differences. Disregard all previous stupidity, Jangkrik.

I'm more stupid than you.

one question how to put the Maps - Earth and the Maps - Space?

Gotcha!'s MP 3 can be found here

Saying this man ripped off Gotcha! is like a lot of people who make scenes are ripping off Data Realms for using their bunker modules.
It'd be ripping off if he had different map objectives but the same map of course.
Creativity comes in different forms.

Anyways, do you plan on making more in the near future?
EDIT: Just realized last update was 2010. Can't hurt to ask tho~

Shouldn't be an issue.
Since you're asking the creator for more content, there is a purpose for this bump.
