How about increasing the chances of infection, if untreated, you`ll be able to join the infected hordes and roam the streets of Chernarus towns and villages. You`ll have all the mannerisms, to enable you to blend in ... hop, crawl, walk, run, etc ... but you`ll only be able to sprint stupidly fast for a brief moment and once every minute or so. Punch, barge and bite could be the attacks, and being able throw items would be a fun thing to do... to freak out passing survivors. Grunts and shrieks to communicate with other zombies, to make them aware of intruders, and to scare the survivors. I would just love to be able to follow survivors around to make their experience harder/better/scarier. If you die you`ll have the option to respawn as human or return as infected. Other smaller requests: 1. More handheld weapons dead rising stylee .. cleavers, hammers, baseball bats, pitchforks. 2. Traps/ trip wires that can be used as motion sensors/alerts. 3. The ability to drink/sip from the ponds/water pumps. Ponds would have an increased chance of infection.
