Well, I am adding 3 types of gameplay, to hopefully get some more replayability out of WorldAlpha Sniper. "Timed" and "Survival" modes are straightforward. It is the 3rd type, I'm struggling to figure out a good name. I'm sure you've played timed games, that get extended when you do something, ie in racing you go through a checkpoint. In the game I've made you will get more time for each sniper you hit. What do I name it? I have "Progressive" in mind but that doesn't sound quite right. Any suggestions?
Marathon is a good suggestion I have a timed mode in my game where you survive an onslaught of enemies and try to beat a certain time, I call it blitz mode
