Kidou Senshi Gundam Gundam vs Gundam NEXT PLUS [Japan]

The Premise of the VS series is to bring your opponents' battle gauge
from 6000 down to zero. Similarly, if your own battle gauge is braught
down to zero, you will get a Game Over. So how do one decrease the
opponents' battle gauge? You do so by defeating ememies. Each unit is
defeated, the cost of the unit will be subtracted from the battle gauge.
More will be covered in the Battle Gauge System section.
