Thunder Force IV (サンダーフォースIV), called Lightening Force: Quest for the Darkstar in the US, is a 1992 shoot-'em-up by Technosoft released for the Sega Mega Drive. It is the fourth game in the Thunder Force series.

Story

Thunder Force IV, Stage Select.png

Stage select

Shortly after defeating the ORN Empire in Thunder Force III, the Galaxy Federation comes under attack by survivors of the Empire, who have gathered their remaining forces on the planet Vios. This new faction has been biding its time and developing weapons even more deadly than those used by its predecessors. The Galaxy Federation must again scramble a new small craft, the Fire LEO-04 Rynex, to counter this emerging threat.

Gameplay

The game is a side-scrolling shooter like its predecessor. The Rynex is moved in any direction using the D-pad. The screen scrolls horizontally automatically. Stages are significantly taller than in previous games, and the player can travel to the upward and downward edges of the screen to reveal a larger playing field. The player can change the movement speed of the ship with A. Pressing the button adds 25% (or loops back to 25% if already at 100%); holding the button adds 1% at a time.

The Rynex shoots with B, which can be held for continuous fire. It is equipped with multiple weapons, which are switched with C. The player starts with two weapons and acquires more by collecting items. The player can change the speed or the equipped weapon while the game is paused. The player can also equip two Claw add-ons, which are two small satellite drones. The Claws block weak incoming bullets and provide extra firepower by firing single, normal shots. Midway through the game, the Claws are upgraded and acquire the Thunder Sword ability. This allows them to charge up when the player is not firing and then release a powerful beam attack with B.

The Rynex is destroyed in one hit from an enemy or an obstacle. Losing a life loses the Claws and the equipped weapon (unless it is a default weapon). The player gains an extra life at 10,000 and 100,000 points and then every 100,000 points after that.

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

Weapons

Thunder Force IV, Weapons, Twin Shot.png

Twin Shot
Fires two streams of parallel bullets.

Thunder Force IV, Weapons, Back Fire.png

Back Shot
Fires one stream of bullets to the front and one stream to the back.

Thunder Force IV, Weapons, Blade.png

Blade
Replaces the Twin Shot with large orange blades. A strong weapon, but the size of the blades make it difficult get through the armor of some bosses to hit their weak spots.

Thunder Force IV, Weapons, Railgun.png

Railgun
Replaces the Back Shot with powerful, long lasers behind the Rynex. The strongest weapon for shooting enemies from behind.

Thunder Force IV, Weapons, Snake.png

Snake
Drops bombs above and below the Rynex at an angle. When this weapon is equipped, rather than providing support fire, Claws leave shadows that provide additional protection.

Thunder Force IV, Weapons, Hunter.png

Hunter
Fires blue energy balls that seek enemies. Less powerful than other weapons but does not need to be targeted.

Thunder Force IV, Weapons, Free Way.png

Free Way
Launches missiles in a conical spread in the opposite direction of the ship's travel.

Thunder Force IV, Weapons, Thunder Sword.png

Thunder Sword
Acquired in the Vios stage. Allows Claws to charge up when the Rynex is not firing; the next shot releases a powerful sword beam, which penetrates through multiple targets, with two additional angled lasers (regardless of which weapon is selected).
