Tell me about the Infected Sharks!
Infected sharks follow you around, eating anything they see. Like a pet, you’ll get Points, Health, Gold and Growth for anything they eat. After a while they explode, damaging any enemies nearby.
What happens when the Zombie Shark dies?
When the Zombie Shark dies, the gases that have built up inside its decomposing body cause it to explode in spectacular fashion. This will damage anything nearby, and you’ll even get Points, Gold and Growth for anything killed by the blast.
