Play Tunnel B1 Online

So, Tunnel B1—imagine you're piloting this sleek hovercraft through these tight, neon-lit tunnels, dodging enemy drones and turrets that pop up out of nowhere. The controls feel a little floaty at first, but once you get the hang of it, weaving through narrow gaps while blasting choppers is weirdly satisfying.

Some sections slap a timer on you, which turns the whole thing into a frantic race against the clock. Mess up a turn, and you're either smashing into walls or getting shredded by gunfire. There's this upgrade system too—nothing crazy deep, but grabbing a better weapon or faster engines makes those later tunnels way less brutal.

It's one of those old MS-DOS games that nails that "just one more try" feeling, even when the difficulty spikes hard. Definitely a relic, but a fun one if you're into retro arcade-style shooters.

Each game uses different controls, most DOS games use the keyboard arrows. Some will use the mouse , "Alt" ,"Enter" and "Space bar".
