Geometry Dash Acid Rush III is a Hard Demon level rated 10 stars with 1 user coin created by Serponge. It is the final and third level in the Acid Rush trilogy, following Acid Rush and Acid Rush II. It is well-known for its extensive use of mixed duals, XL length, and varied timings. The first Acid Rush was based on an acid trip, the second around sewers and acid, and the final around a nightmarish future of cities where acid has ruined everything. We made a few references to the initial acid rushes and doubled the length for an epic finish in this ostensibly final masterpiece! Acid Rush 3 is well-known among Geometry Dash gamers and is often regarded as a must-play level.
