Deadly Clubstep was made by IIINeptuneIII (NePtunE). It is a difficult demon level full of memorization, timings, and skill-based UFO and ship segments. Due to this, it is generally considered a Very Hard Demon o Insane Demon. Some very skilled players consider this level a Hard or Medium Demon.
The level starts with a memory-based cube segment, with many fakes and some tricky timing, but is easy after practicing the second half, the real memory based part of the cube. Then later the drop of the level begins with a double speed ship containing jump orbs, tight flying, and invisible spikes. It then goes into a buggy transition into the ball part, which has many fakes, and later goes into a slow ball mode with tight timings. Then there is a tight ship segment where you have to go into an area that looks like one space flying but has invisible blocks to make it easier. A mini UFO segment follows, similar to the real Clubstep, and is fairly easy. Then there is a memory-based cube segment. Then there is a tight ship segment with several gravity portals. This is followed by a tight UFO section with several gravity portals and some timings. Then there is another ship part with gravity portals and several jump orbs. Then there is a mini cube with lots of memory. It then has a timing-based ball part, followed by a ship part at the end of the level, showing the creator's name.
- At 35% the transition into the ball part is bugged, resulting in the player smashing into the spikes. The bug can be avoided, but this maneuver is difficult to pull off.
