Improvements are also unlocked with each level. Upgrades can either increase projectile damage or increase the ammo. As you progress through the levels, you will unlock new types of weapons, such as a shotgun, machine gun, or bazooka. Hero Ring is a 2D-platformer arena shooter in which you have to destroy the monsters that appear from the portals. Firearms will help you with this. A shield may also appear after reloading a weapon. Enemies can be very different: some of them walk on the ground.
