There are three racetracks in the game that can be played solo as a time trial, or as mutiplayer racing with up to four players.

1: Stardust Speedway

  • Difficulty: Easy
  • Description: Stardust Speedway is shaped like a rounded square, with a large hole in the middle of it.

2: Cosmic Collision

  • Difficulty: Medium
  • Description: Cosmic Collision is shaped as a square, with an upward curve on the bottom side. It has sharper and a larger number of turns than Stardust Speedway, along with two bumpers.

3: Space Hopper

  • Difficulty: Hard
  • Description: Like Cosmic Collision, there are quite a few turns in Space Hopper. This time, however, the track is separated into 3 parts which players have to jump from one to the other. To do this, players need to boost themselves over a springboard at the end of each part. If unsuccessful, players will fall off.


There are three objects that appear in the game.


Meteors are falling hazards that appear on all three tracks, signaled well ahead of time by a shadow on the track. On impact, they will turn to dust and flatten any UFOs underneath it. Players will lose control of their UFO for a brief moment before it returns to its normal form.


Bumpers are interactive objects that only appear on the Cosmic Collision track. When players hit them, they will bounce off in a different direction, depending on the angle of the hit. With skill, players can use them to their advantage.


Springboards are interactive objects that appear only in the third track, Space Hopper. They spring the UFOs upward and forward when players run over them. Players can travel over gaps in the track by traveling over them with quickly.


In single player time trial, Players are scored on the amount of time they take to complete the track. The high score list does not show the top scores, rather, it shows the first 100 players who have completed the track in the shortest time.

Unused content

Go Go UFO contains a large amount of unused content, mostly in the form of unused text. It is notable that what is possibly beta Go Go UFO text is present as unused images of text in Snow Drift, of all the unused images in Snow Drift only one of these images appearing in Go Go UFO (also unused).

Unused grey coloured text

Go Go UFO contains unused text from Dirk Valentine, although some of the text is also unused in Dirk Valentine. Present in the game's image files are images of grey coloured text, all text being unused and lacking a used equivalent. Unused grey coloured images of text include a forward slash (/), starting quotation mark ("), British Pound symbol (£), and a hyphen (-).

All of this text except the British Pound symbol is at the regular size of all other used text.

Unused different green coloured text

Also present in the game is an unused backwards slash that appears to be the same size and fit in Go Go UFO, however, the outline is darker in colour than the used font.

Interestingly, this image is also present as unused text in Snow Drift, among other text using the same font seen in this unused text (also unused in Snow Drift). It is possible that the unused text in Snow Drift was early text for Go Go UFO.

The unused text in Snow Drift that have the same colours as this unused text are a forward slash (/), equal sign (=), a starting quotation mark (“), a starting bracket [(] and ending bracket [)]. Although Go Go UFO also has an unused quotation mark and forward slash, they are different from the unused Snow Drift ones.

Furthermore, the unused brackets present in Snow Drift barely resemble the unused Go Go UFO brackets. None of this other unused text is present in Go Go UFO.

Unused green coloured text

Present in Go Go UFO's image files are images of text, these images using the same colours as regular used text, but are not used at all throughout Go Go UFO. Unused is a plus sign (+), comma (,), apostrophe (appears the same as a comma), a starting bracket [(], an ending bracket [)], and a question mark (?).

Notably, the unused apostrophe and unused comma have the same sprite, despite being two separate images. However, the apostrophe's sprite is raised higher than the comma. The unused brackets are different than the ones seen in the "(c) nitrome ltd 2008 (" image seen at the bottom of the menu. Furthermore, the unused similarly coloured brackets in Snow Drift may be beta versions of these unused brackets, considering how the Snow Drift brackets tend to fit more with the Go Go UFO theme.

Remnants of unused text

Present in the image files of Go Go UFO are images that are completely blank. However, they do have a name, and these images are among other used text. There are three remnants of unused images of text (all information is assumed from the file name): an exclamation mark (!)(image is titled "text2_exclamation"), a period (image is titled "text2_stop" ; fullstop is the British name for a period), and an equal sign (=)(image is titled "text2_equals").

The blank image titled "tex2equals" may have originally been the unused equal sign that is present in Snow Drift's code.

Unused/beta track

Each track of Go Go UFO has a track mask and track guide, each image being a large image of one colour that could fit on top of the entire track, across all solid platforms. Track masks have their image file named "track_mask", with an underscore after "mask" connecting the word "mask" and the number of track mask together.

All track masks are pink, with the exception of track mask 1, which is white. Also existing are images titled track guides, each track guide having the word "track" and "guide" in their name, with a number between each word, this number connected by underscores. Track guides are all coloured white, and appear exactly as track masks.

It is not known whether they are unused or are used for the construction of tracks. While Stardust Speedway uses track_mask_1[2] and track_1_guide[3], Cosmic Collision uses track_mask_2[4] and track_2_guide[5], and Space Hopper uses track_mask_3[6] and track_3_guide[7], there is present in Go Go UFO's image files a large white rectangle with smooth corners, this rectangle having a small door-like opening close to the bottom of the rectangle and a medium sized opening close to the top of the rectangle.

Due to the size of this image being the size of a regular track, it is likely that it is the remnants of an unused track, this image likely being the unused track's track guide or track mask. Although it being an unused track is plausible, it is also possible it is a beta version of Stardust Speedway, considering its white colour, similar curved corners, and placement of their gaps.

If this is in fact an early version, it is likely that this track mask/guide was made very early in Go Go UFO's development, as where all tracks track map/guide can easily tell the course that is taken on the track, this track map/guide does not have any sort of indication of the course the player would take. The lack of course for the player to take may imply that this course was meant to be more hazard or unhelpful obstacle based, consisting of many of these objects placed around the course that the player would have to avoid.

Alternatively, this entire course could simply be a test course.



  • Go Go UFO and Calamari are the only Nitrome games so far that are both a mini and multiplayer games.
  • The third racetrack, Space Hopper, shares its name with another Nitrome game. However, it might be a cameo.
