A green Medkit the most obvious alternative colour to a red medkit, this is the colour i think Medkits should be.
Just extract the files to (or wherever your l4d2 is installed)
E:\Program Files\Steam\steamapps\common\left 4 dead 2\left4dead2\materials\models\
I know it says 'radkit' but that because edited the file on l4d1 and couldn't be bothered to change its name (its not in anyway a copy from the Radkit)
