Grobda

Grobda is a multi-directional shooter arcade game that was released by Namco in 1984. It is a spin-off from Xevious, as the player's tank (the eponymous "Grobda") first appeared in that game as an enemy.

The player controls Grobda, a tank trapped in an arena filled with numerous indestructible obstacles - and several enemy tanks. Whan an enemy tank is killed, it will cause an explosion and any other enemies that happen to be in the blast radius at the time will also suffer the same fate. But if Grobda is too close to the explosion, it will also be killed. Grobda has a shield that offers very temporary protection from enemy fire, but this will soon disappear if it is constantly under attack.
