No, it's not Ebola, or acne. Breakout is my own mash-up of Jailbreak and Net Monster.
All players begin on one baseline. Coach feeds ball to one player at a time. If player misses, he/she comes over to coach's side and plays at the net. If net player hits a winner, he/she is back in line.
You can accommodate 5-6 players at net safely on 60- or 78-foot court; 4-5 on 36-foot court max. If you get more than this, don't do it - it isn't safe. Just have the extra players wait until a spot opens up for them when another player hits a winner and rejoins the line.
Goal is to be the last player standing on the original end (not the net side) and hit a ball in that is not intercepted by the net players.
