I was thinking about making Dead Space like game.
My question is simple. Which scripts should I use? Which will be the best?
I have to make different weapons, life bar, Oxygen Bar, action style fight.

Resources which I need :
Space themed tiles and objects and characters(Issac, some good person and 3 kinds of necromorphs.
Music and sounds I can get on my own.

Please tell me and give me some links or advices.

I have experience with making games on RPG VX maker.

It's perfectly possible to make a Dead Space ABS, from what I know about it. It would take... well, RPGXP is the better choice for ABS systems, but there are a few good scripts out there for VX as well - Versus Tempus Proelium is an example; however, the tank-like controls make it better suited for an early Resident Evil title. An oxygen bar could be evented with some significant effort, but you could just use that latent MP bar in an ABS script if you were crafty.

Can't help you with the sprites and tiles, I'm afraid. However, I have a small hint: horror is about creating atmosphere. Monsters creeping through the vents, creative use of light and hard shadow, BGM and BGS that matches the action going on... all of this can create an atmosphere of terror. Don't take my word for it - play through a few successful horror games/movies and learn from them.

Good luck on your project, man!

Yeah, I have played many horror games and I have watched many horror movies.

You are right about the atmosphere.

I have found some tiles that will be perfect for my project, but I need Isaac Clarke sprite and 2-3 necromorphs.
Any Idea who could make VX sprites for me?
