Game description:

Borderline is a 1981 overhead military action game developed and published by Sega, playable here as a browser emulation of the Sega SG-1000 home port. You command a jeep pushing through enemy-held territory, taking on waves of infantry, armored units, and aircraft as the landscape scrolls past.

How to play

Steer your jeep with the arrow keys and fire with Z (Button A). X (Button B) triggers a secondary action. Press Enter to start or reset. Fight through each wave of attackers to advance — the mix of ground troops and aerial threats keeps you covering multiple angles at once.
