Guardian (1986). Play online

Summary

Guardian roared onto the arcade floors in early 1986, a gritty side‑scrolling beat ’em up that let you pilot a lone robot across six alien worlds.
The cabinet’s four‑way stick and punch‑plus‑kick buttons let you crouch, jump and strike from any stance, while glowing cross‑shaped icons flash extra energy, temporary invincibility or a long‑range laser, and a red orb can triple the robot’s punching power.
Each planet ends in a memorable boss, and the game rewards deep‑cut secrets for high‑score chasers with a checkpoint system that drops you back to the last save point rather than a hard reset.
Though Toaplan’s graphics newcomer Kōetsu Iwabuchi and composers Masahiro Yuge and Tatsuya Uemura gave it a distinct visual and audio flavor, the title flopped commercially and vanished after its arcade run, only resurfacing decades later on Switch, PS 4 and Evercade via the Kyukyoku Tiger‑Heli and Toaplan Arcade 1 collections.
Today the rights sit with Tatsujin, the Toaplan legacy label owned by the Embracer Group, and a nostalgic soundtrack album finally landed in Japan in 2018.

Storyline

In Guardian, you step into the chassis of a lone combat robot tasked with wiping out relentless waves of alien foes. The arcade shooter thrusts you into a sleek, futuristic sci‑fi backdrop where every shot echoes across metallic corridors.

The adventure spans six separate planetary locations, each designed with its own visual flair and enemy roster. As you clear each zone, a towering boss awaits, demanding precise timing and firepower before you can move on to the next world. Defeating every boss unlocks the next stage, culminating in a final showdown that tests everything you’ve learned.
