Thunder Force III (サンダーフォースIII) is a 1990 shoot-'em-up developed by Technosoft for the Sega Mega Drive. It is the third game in the Thunder Force series and the first to debut on a Sega console. It was brought to the arcades as Thunder Force AC.

Story

The story takes place immediately after the events of Thunder Force II. Despite their successes, the Galaxy Federation has not been faring well in their battle against the ORN Empire. ORN has installed cloaking devices on five major planets in their space territory that conceal their main base, making it difficult for the Galaxy Federation to locate and attack their headquarters. Also, ORN has built a remote defense system to protect itself named Cerberus, which is especially efficient at neutralizing large ships and fleets. Knowing this, the Galaxy Federation creates the FIRE LEO-03 Styx (also transliterated as Stukks): a craft small enough to avoid detection by Cerberus, yet equipped with the firepower of a large starfighter. The Galaxy Federation deploys the Styx on a mission to destroy the five cloaking devices, infiltrate the Empire's headquarters, and destroy the ORN Emperor, the bio-computer "CHA OS."

Gameplay

Stage select

Thunder Force III is a side-scrolling shooter. The the free-directional, overhead stage format from the first two games in the series is removed and replaced entirely by the horizontally scrolling stage format for this game and all subsequent entries. The player chooses which of the initial five planets (Hydra, Gorgon, Seiren, Haides, and Ellis) to start on. After the first five stages are completed, the game continues for three more stages into ORN headquarters.

The Styx is moved in any direction using the D-pad. The player can cycle through four speeds with A. The Styx shoots with B, which can be held for continuous fire. It is equipped with multiple weapons, which can be switched with C. The speed and weapon can be switched while the game is paused. The player starts with two weapons and can acquire more by collecting items. The player can also equip two Claw add-ons, which are small drones that revolve around the ship. The Claws block weak incoming bullets and provide extra firepower by firing single, normal shots. Unlike the previous game, both Claws are equipped at the same time rather than separately.

The Styx is destroyed in one hit from an enemy or an obstacle. On Normal difficulty, losing a life only loses the equipped weapon (unless it is a default weapon). On higher difficulties, losing a life loses all acquired weapons. On all difficulties, losing a life loses Claws. The player gains an extra life at 20,000 and 50,000 points and then every 50,000 points after that.

There are three selectable difficulty levels (Normal, Hard, and Mania). The options menu is accessed by holding A, B or C when pressing  START  on the title screen.

History

Thunder Force III was released in the US, Japan, South Korea and Brazil, but it is not thought to have been released in the pan-Euro area. However, the US release is known to have been distributed in limited numbers across France and Germany, with the instruction manual exchanged for localised versions[9]. Official releases in other PAL regions have not been confirmed.
