So I had this idea for a gametype that there would be custom power-up with a long time delay that only the zombies could use. I came up with the idea that the zombie would (roleplaying wise) be like the girl from the FEAR series. So I was wondering what would be good traits to give the custom power-up in order to support this idea? There are two ideas I had for this character: 1. That "sara" would be fast and deadly, with a forced red color. 2. She would be strong and invulnerable but would do little to no damage to the players, with a forced red color. If you have any other ideas or opinions on this please post them.
