added new splitscreen option which will only work if the player 2 character is alive, if killed you will have to restart and then press the option again, the 2nd player uses controller, switching weapon for 2nd player is still buggy so u will have to press L1 and use up and down dpad to scroll on weapons.

also i added an elevator door to on naissur to make it more impressive.

also added helmet cam like those in real life, trigger on by pressing h, make sure post process is set to high for best experience

also added better zombie behavior and improved game performance overall
