F.I.R.E.

Description
F.I.R.E. (Fast, Ingenious and Risky Elimination) is a horizontal scrolling space/planet based shoot-em-up. Your space-ship starts the game moving slowly, and with a low rate of fire. Upgrades can be obtained to increase speed, rate of fire, adding a laser, or providing a shield which makes you invulnerable for a fixed period of time. The upgrades are earned by collecting circular tokens with a B on them, which can be destroyed by shooting them. The upgrade system is Gradius like, so once the required number of tokens are collected, the particular upgrade can be selected.
The player starts with three lives, and each time a life is lost the power-ups are also lost. There are four levels in total, with a "boss" located at the end of each. After destroying the final boss, the levels repeat.
