Currently in development for the Sega Master System is Frontier Force – a fixed screen shooter by developer, BadComputer.
Your character has access to 6 weapons. The primary weapon has 4 options, plasma, flame, missiles, and chain gun. The plasma has unlimited ammo, the rest can be replenished with ammo pickups.
The two other weapons are the laser and the bomb. The laser has limited ammo but can be charged by damaging enemies with the other weapons. The bomb is a one-shot explosion and also has limited ammo.
- Flame: high damage against ALL enemies but limited to close range.
- Missiles: high damage against MEDIUM-sized enemies.
- Chain: high damage against SMALL-sized enemies.
