Projex is a Valve's Portal Mod which is a personal creation that tributes the fabulous game of Portal. This is more of a skin rather than a real-game Mod of Portal, with additional puzzles. No scripts and or codes, I customized the MOD to adjust the look of the game and create basic puzzles for Level Design. This is a Beta version; the graphics are not polished, but publishable. Level design is functional but, not fully tested on a large audience. Projex is for the advanced players, whom have completed and knowledgeable about Portal. Beginners will encounter above average puzzles that are not difficult.
