The player has several weapons that can be freely switched (forward shot, back shot, and missile), and can also change the speed of the ship. Enemies come from all directions, and certain waves will drop powerups, including shields and weapon upgrades. The player needs to collect five upgrades in order to improve their weaponry, but the upgrade affects all three weapons.
The game includes eight stages, most of which include both a midboss and a boss at the end, and three difficulty settings. There is also a minigame similar to Whack-a-Mole where there is a grid of ship icons, and the player must hit the rotating ships.
Eliminate Down gameplay
Reminiscent of Hellfire, the Steel Pyron has three firing directional weapons all ready at the player’s disposal: a forward firing blaster, a rear laser attack and diagonal, four-way firing bombs.
The forward firing attack also has the Super Crash Shot, a small white straight-firing rocket, that with upgrades changes into a long white laser beam that can fire through foreground objects. Unlike Hellfire however, the game has no checkpoint system, though the game makes players restart a level once they lose all of their lives.
Extends are set at every 100,000 points.The weapons are upgradeable by collecting Power-Up icons; obtaining a certain number of Power-Ups level-ups the size and strength of the player’s weapons, but the weapons are upgradable to just three different levels.
The only other defenses the players has is a shield pick-up called the Barrier that protects the ship for at least two hits. The A and C buttons allow the player to switch among the three weapons.
Players can also change the speed of the ship by pausing the game and adjusting the speed level on the pause screen.Eliminate Down also has a mini-game playable at the main menu similar to Concentration where players have to find the right image under a certain time limit.
