Achtung, die Kurve!, also known as Zatacka or simply Achtung, is a freeware, multiplayer DOS computer game that supports from two-player up to eight-player gaming simultaneously. The game is a clone of the lesser known Cervi (Worms) from 1993, differing in that the lines now have holes. Author is Filip Oscadal, aka Fred Brooker, from the Czech Republic who made this game, together with Kamil Dolezal, for Amiga incl. music, sound effects and gfx background (worm speed depending on the picture). The game is supposedly from 1995 and written in Borland C++. The title is in German.
