Thunder Force II is a 1988 shoot-'em-up developed by Technosoft for the X68000, and the second installment in their Thunder Force series. The following year, it was ported to the Sega Mega Drive as Thunder Force II MD (サンダーフォースII MD), and this version was released worldwide as simply Thunder Force II. It was the first third party Sega Mega Drive game.

Story

Thunder Force II, Introduction.png

Fire LEO-02 Exceliza

After the events of the first Thunder Force, the defeated ORN Empire decide to attack the Galaxy Federation again. The ORN Empire creates a powerful new battleship, the Plealos, which they use to destroy the planet Reda and take the planet Nepura as their own. Eventually, the Galaxy Federation learns that ORN houses Plealos deep below Nebula's surface when not in use, and they set out to destroy Plealos with a new version of the powerful "Fire LEO" fighter craft, the Fire LEO-02 Exceliza.

Gameplay

The game is a shoot-'em-up whose levels are split into two gameplay styles: top-view and side-view stages. Top-view stages are the free-roaming, overhead stages from the original Thunder Force. The screen constantly scrolls in the direction that the ship is facing. The objective is to locate and destroy the cores of four enemy bases. Side-view stages play like a traditional side-scrolling shooter; the screen constantly scrolls to the right. The entire stage does not fit on the screen, so moving up and down reveals more of it. This would become the only format in subsequent entries of the series. Each level begins with a top-view stage, then progresses to a side-view stage, which concludes with a boss encounter. The final stage solely uses the top view.

The Exceliza is moved in any direction using the D-pad. It shoots with B, which can be held for continuous fire. It is equipped with multiple weapons, which can be cycled left with A and right with C. The player starts with two weapons and can acquire more by collecting items. The top-view and the side-view stages have different sets of weapons. The player can also equip up to two Claw add-ons, which are small pods that revolve around the ship. The Claws block weak incoming bullets and provide extra firepower by firing single, normal shots.

The Exceliza is destroyed in one hit from an enemy or an obstacle. Losing a life also loses any acquired weapons and Claws. The player gains an extra life at 20,000 points and then every 50,000 points after that.

History

Release

The Swedish version shown below has an interesting story behind it. The distributor in the Nordic countries was Playmix/BRIO, famous for its classic wooden toys and unharmful playthings. This is the first and probably last time they used censorship on a game. The missiles on this early game's front were considered too violent and the picture was replaced by the ship from the Japanese version instead. After they mixed it together, they simple photographed it and printed it on Fujicolor paper (can be seen on the back of the inlay). This version is therefore fairly common in Sweden.
