HELP!! I lost everything.

Please Help me, i lost the most important scripts in unity for my games and i need your help.

The scripts are:

FPS Walker and another script used for moving in 2D games.

Please help i'm in the final stage for my game.

FPS Walker is a standards asset script - go to your unity install directory, look in standard packages, then double click Standard Assets - it'll load a screen in unity letting you select which files you want - just click clear, then find the fps walker and select, then import

For the other script - you'll have to be much more specific, there are many ways to move in 2D

Just restore from your latest backup. If you're not using any version control or backups, you're basically crazy and are asking for trouble, if you're even a little bit serious about what you're doing.
