SvitlaSveta4: Hi to Community :). Really want to know how different is this game from the original (PS2 version) - not only by graphic, but also maybe new mechanics and some other things?
Apparently, the remake includes a new mission level (The Wrong Stuff) not found in the original game: it takes place in Area 42, the game's version of Area 51.
Also, the control mechanics and ui hub have been simplified for a smoother experience: for example, psychokinesis can be activited by simply holding and releasing the right mouse button; when flying the spaceship, you can now use the right mouse button to fly the spaceship vertically, bringing it closer/further to the ground.
Here's a video explaining the new gameplay mechanics and ui improvements:
