A refreshing departure from slower, more methodical tank shooters such as Combat and Armor Ambush, Grobda will grab ya with its fast-action objective of speeding around the screen, firing away at wave after wave of enemy tanks. The player's tank can emit a shield, but it consumes energy and will only recharge when not in use. Each playfield in this game consists of a different arrangement of barricade-like squares, and an electronic voice tells players to "get ready" as each round begins. The first few levels are easy as players can simply keep the shields up while destroying the handful of onscreen enemies. However, the action gets brutally difficult after a couple of minutes because the rounds get faster and more crowded. Interestingly, the titular tank was originally an enemy in Xevious, making this lesser known title a spin-off from the highly influential shooter.

Roots & Influences
Grobda was probably influenced by the success of the Atari 2600's Combat cartridge and the tank sequences in the coin-op classic Tron.
The player controls a tank in an arena filled with numerous indestructible obstacles - and several enemies such as tanks. When the player kills an enemy, it will cause an explosion and other enemies that happen to be in the way at the time will share the same fate as the first one. But if the player's tank is too close to the explosion it will also be killed. The player's tank has a shield that offers temporary protection from enemy fire, but constant firing from enemies will make it disappear. Each level is called a "battling", and there are 99 in total. If all 99 battlings are beaten the high score table will show that you have beaten 100 battlings. There is also a level select screen.
The game runs on Namco Super Pac-Man hardware but with a DAC for speech. Each stage begins with a voice saying "Get ready!".
