Shortly after defeating the ORN Empire in ''[[Thunder Force III]]'', the Galaxy Federation comes under attack by survivors of the empire, who have banded together to form a new threat, Vios. Vios turns out to be more powerful than ORN ever was, and the Galaxy Federation must again use a new small craft to destroy their base on the planet Aceria.

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==
−
Gameplay is almost identical to ''III'': {{B}} shoots (you have rapidfire), {{A}} changes speed by 25% while holding the button down constantly adds 1%, {{C}} changes weapon, and powerups are collected from enemies. Unlike ''III'', however, you are not fixed to the camera motion; holding {{up}} and {{down}} will take you higher/lower than the screen limits (as in ''[[Thunder Force II|II]]'').
+
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 default 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.

*Boss: A giant ship with a fin on the bottom that shoots fireballs at you. Hit it enough and it will detach from the ship, revealing a free-moving sub-ship that will attack you in a variety of ways. Due to collision detection on the boss' weak spot, it's very difficult to damage him with the "Blade" weapon.

===Tips and tricks===
 
−
*The game has at least two score exploit points. The first is at the enemy just before going underwater in Strite. I constantly releases small enemies. The second is in the final stage, Versus. Keep playing until you reach the large cannon, which you normally must destroy to proceed. Power up items and 1UPs will keep respawning forever. Whether this was by design or an oversight is not clear.

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 default 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.
