Achtung, die Kurve!

Achtung, die Kurve!, also known as Curve Fever or simply Achtung, is a freeware, multiplayer DOS computer game. It supports from two-player up to eight-player gaming simultaneously. The game is a clone of known Cervi (Worms) from 1993, differing in that the lines now have holes. Author is Filip Ošcádal, aka Fred Brooker, from the Czech Republic who made this game, together with Kamil Doležal, for Commodore Amiga including music, sound effects and graphical background (worm speed depending on the picture). The game was written in Motorola 68000 assembly. The original DOS game is supposedly from 1995 and written in Borland C++. The title is in German language.

The game is similar to the game Tron, where players leave a trail and try to make the opponent hit a wall or a trail first. The game is controlled by only two buttons, to turn left or right. A key difference is that in Achtung, die Kurve!, players can turn and travel in any direction. It is not limited to the four cardinal directions.

Each player spawns as a dot at a random spot on the playing field, move at a constant speed. Each player has the ability to turn left or right. Because turning speed is limited, sharp turns are not possible. As the dot travels across the playing field, it draws a permanent, solid line in its wake, in the color of that player. When the dot collides with any section of line or the boundary of the playing field, the player instantly loses, although the line remains in the playing field until the end of the game.

Achtung, die Kurve becomes increasingly difficult as more of the playing field is blocked off by lines. Other players may try to draw barriers to block the path of other players, forcing them into a collision. However, as the lines are being drawn, gaps are occasionally being generated that can be used to escape a section of the map that has been blocked off. The game is won when all but one of the players has collided.

In its original version, there are a total of six different lines. Up to six people can play at the same time. All the lines are exactly the same, the color being the only thing setting the different lines apart. All the keys on the keyboard must be used to play this game as it takes a lot of skill and talent.
