Submission Comments
This is a sequel to Out of This World starring an alien. Some scenes have graphic violence, so the TAS is not suitable for anyone.
You need Sega CD BIOS 1.10 (USA) to run the file correctly. If you have any desync issues, try another version of the game. If the problem remains, give us the details of the occurrence, so that a highly skilled team of TAS synchronization squids can be sent to your aid.
Note: There exists a version of the game with badly synchronized music files. It makes the ending cutscene sound bad.

Game objectives

  • Emulator used: Gens11a
  • Aims for fastest time
  • Abuses a programming error in the game


If something looks strange, it's probably for adjusting the position for better screen transition. Many times, the only thing that matters is how fast the individual screen is exited, because the character position is often fixed after a screen transition. It is not trivial to optimize, though, so I would be glad to see this improved in the future.
Soon after planting the bomb, I use extra screen transitions to advance the bomb timer faster. It may look stupid, but saves 9 frames of waiting time.
Two cutscenes are skipped in the run. Some people might prefer a version that includes the cutscenes, but one of them can be watched in the beginning of the game with no effort and it takes almost as long as the TAS itself, so I thought it was better this way.
Sorry for the lack of motivation to write a better submission message. Please ask for more explanations, if you need any.
Thanks to White Label, nitsuja, klmz, upthorn and nfq for useful comments.


mmbossman: What a goofy, and somewhat chilling, movie. I'd expect nothing less from you, Aqfaq :) Accepting for publication.
