I'm looking for something very simple: in my game there's an orc attack in a town you have to defend. There are many orcs wandering through it. The thing is that these encounters are optional but you get rewarded depending on how many you killed. I put a "maybe we should defeat the orcs before we move on" dialogue line, but I think something more obvious would be better. So, what I needed is that during this event a counter will show up in upper right corner that says "Orcs defeated (variable)/10" or something to that effect. EDIT: I am aware I could do this using pictures, but the lazyman in me still had to ask.
