@ratchet: thank you for some ideas, but my aim isn't to make something Battlefield 3 or COD type games. I only want to make simple, horror project, with some simple old school graphics. So, I don't aim to bring such stuff as destructible environment and as I'm not a level designer that level was used only for testing purpose. I'm looking for a designer to take care of that part of the project.
@Rei_Ayanami: I agree with you, but as I said in this post above, I don't aim at compiting with such game monsters as Battlefield 3 and COD series, that will be ridicules
