Target Shooting mode in shooters

Had an idea for a good mode for shooters a little while back that would fit well with a lot of games, but particularly well with character based “hero shooters”, where characters have various move-sets, as well as fast-paced 'movement-shooters'. 

The mode involves target shooting, but that can be done in a lot of ways 

Let’s start with the what and the where: 

• The target could be stationary, or it could move. 
• Maybe they slowly float away, like a balloon. 
• Maybe it shrinks. 
• It could also be solid and grant you points as your team damages it and grant bonus points for getting in the last shot before breaking it. 

As for how they appear, it could very from racing to a single target, to many targets being on the field at once. 

If there are multiple targets, here are the ways it can go:

• All the targets appear on the field in the beginning
• More targets appear over time. 
  • Either as they're destroyed or as time goes on (or both)
• There can be 'phases', where all active targets disappear after a certain amount of time, and new targets appear elsewhere

Of course, most of these work best with stationary targets that can be destroyed quickly, but that doesn't mean people shouldn't be creative.

Regardless of that though, the targets should be easily spotted, and maybe even marked on the map.

I feel like a mode like this could be very interesting and bring a lot of intense, fast paced energy to a lot of games
