by Keon - Jam Entry

Abduction is an arcade "upgrade-em-up" in which you control an alien UFO and abduct humans for research. Each round lasts 30 seconds, during which you must abduct as many humans as possible. In between rounds, you upgrade your ship and unlock powerful special weapons to challenge the increasingly harder waves of enemies. An average player should be able to unlock everything in 15-20 minutes.

The audio for the game not mine, and full credits for the sources of the audio tracks can be found under /res/sfx. Everything else was created and programmed by me.


The game has been tested on Windows 7 and 8, but is currently untested on Mac and Linux. If it does/doesn't work on either of those systems please let me know. Abduction is a java game and will require a working JRE to run.

To setup, download the zip file from the given link. Extract the zip and run the .jar file. Alternately, if you are on Windows, you can also run the .exe file.

WASD or Arrow Keys: Move UFO.
Spacebar - Hold to use tractor beam.
Mouse - Move to aim, left click to shoot plasma blasters.
E: If owned, deploy microsingularity superweapon.
R: If owned, deploy mind control superweapon.
T: If owned, deploy wormhole superweapon.

Update 1.1: 8:51 PST should now work on Linux.
Edit: Added "all platforms" and "source" links. I was deprived of sleep when I submitted and didn't notice I could change the downloads. Sorry for confusion.

OSX folder contains only some exe files and jar. No OS X game there.

I liked it. Would have wanted a web version as well. Good job

Looks good. But when I open OS/X build, there is a EXE file. How to play it on Mac.

Great work! I enjoyed the mechanics and controls. Only I can say is that the UFO moves like it's on ice.

I liked the part where I was a flying saucer.

@A_K and AntonyBaasan:

I was lazy - all Windows OS/X and Linux link to the same thing. The jar should be a runnable jar - you can the jar itself either by double clicking or if that fails doing java -jar Abduction1.1.jar. If that doesn't work for you let me know, I can make you a .app, but first let me know if the .jar works for you. A friend tried it on mac and said it worked running the jar.

Sorry for the confusion, and I hope this helps.

That was fun. Really cool made and fun to play. I like all these various usages for humans.
Sounds and graphics are also fitting well.

Nice game, although it took me a while to realize I'm not supposed to kill all the humans, but capture/abduct them. Heh, I should have read the description first. I accidently skipped the tutorial pages. Anyway, I had fun with this game.

I had this exact same idea a couple of years ago, and the design of the ship was almost the same :o incredible. Nice job

Awesome audio and mood

I loved slowly lifting up soon to be abductees. This is a good simulation of our impending UFO apocalypse.

You have to use the .jar to open it on Mac OS X
I played it on Mac! I love your game, I give you 5 stars at every point! I win the game. Very very good game!

Quite a fun game! Really enjoyed the upgrade progression, nice combination of fighting and abducting. Never felt like I was in too much danger, so perhaps more enemies would've added to the challenge (flying enemies?). Really good effort, definitely had fun with this one!

Great, would like to have more enemy types

Good job! Just out of curiosity, is it possible to abduct every human in a level?

Keon says ...

@jcourt: On the earliest levels (before tanks start showing up) I've gotten every human once or twice, but on later levels no. The problem is some more spawn in the sides during the game, so if you clear an area you have to go back again to get the new spawns. If you get lucky they all spawn on one side and you can grab them then, but often you have to run back and forth and will probably miss one or two.

On the later levels not at all.

Mini Submission FAQ

TEAMS: Teams entering the Jam should pick a single representative to submit your game, or create a team specific account you can share. We currently do not support Team Voting, but sharing an account and together playing and rating games is acceptable.

CAN I ENTER BOTH EVENTS?: You should pick 1 event, whichever you think it’ll do better in. If the idea is strong, and everything plays well enough, you can go Compo. If you’re a perfectionist, and would prefer people to play a more polished game, do the Jam. Historically, more games are entered in the Compo, but with more people and more time, Jam games have the potential to be better (that doesn’t mean they are). Many solo participants do enter the Jam.

If you made 2 games, unfortunately, the website doesn’t support multiple submissions per user. To submit your 2nd game, you will have to make a 2nd account. Only do this if you made 2 games. Alternatively, if one game is better than the other, then consider just entering the better game.

CAN I KEEP WORKING UNTIL THE DEADLINE?: Yes! Immediately after the 48 or 72 hours, we do something called Submission Hour. As the name suggests, it’s an extra hour for you to package, upload, and submit your games. If there were catastrophic issues trying submitting your game, or you misunderstood how submissions work, that’s okay. It happens. We’re flexible. If you need advice, check with the folks on IRC. If you need an admin, get in touch.

CAN I KEEP WORKING ON MY GAME?: Oh definitely! You should! But for the sake of judging, keep the Compo or Jam version around. You can include a link to the Post-Compo/Post-Jam version of your game on your games page, but sure your main links are the original version.

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate at least 20 games to improve your visibility (Coolness).

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crashes, win condition, or tiny bugs after the deadline. In a sense, this is like “porting” to support more players. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just fixing mistakes you should have caught had you been better rested.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs ( and you will show up. Alternatively, if you just posted it, wait a minute. The cache may not have refreshed yet.

NOT LOGGED IN?: If you get a message about not being logged in, even though you are, it’s because your web browser cached the non-logged in page. You can fix this by either refreshing your cache or clearing your cache. CTRL+F5 in many browsers. Chrome is a bit more work. Press F12 to enable Developer Mode, then you can right click on the refresh button and select “Empty Cache and Hard Reload”. This option is unavailable if you are not in Developer Mode.
