Ten years ago the zombie threat started. No one knows where it started, but within days every continent had an outbreak. Those that survived the initial attack made their way to Greenland to regroup and plan their offensive. The time has come to reclaim the Earth. Most of the zombies have been rendered immobile by natural disasters, accidents, and general decay. There are still small groups roaming our cities, and it is time to wipe them out. Your job is to demolish the remaining cities with a heavy zombie population. This will be a difficult mission as the plane can only carry four bombs at a time. Using your targeting software, you must level each city so it lies below the ‘Red Zone’, enabling ground forces to come in and clear the area. Obliteration is a hand drawn game that is fun for people of all ages. Featuring one touch game play, anyone can pick up and play the game. ************ Features ************ * 35 levels spread across 7 stages * Game Center Leaderboards * Physics based destruction * Tiny Tiny Zombies! ************ Instructions ************ * Tap anywhere to drop a bomb. * Tap again to explode the bomb, or let it hit the ground. * Get the 'city height' (white) line below the 'red zone' (red) line to complete each level. * You get a score bonus for knocking building pieces into the sky or off the screen. * Bombs are affected by the direction and speed of the wind.

Adverts between levels. Adverts on launch. Adverts adverts adverts. ### 1/5 — Fun game but way too many ads *2016-11-14, version 3.4.1* I really enjoy this game and have played it for years, however, the ads have gotten to be just too much. It was bare-able when it was every few levels, but now it's every time I clear a level. Plus the screen is too large for iPad. Sometimes I can't tell where something is blocking my ability to clear the level because it is somewhere on the sides and doesn't show on the screen. Note to the developer, will you fix the issues please. I'd even be willing to pay for a version that works right and has no ads. It seems to me that if you can take the time to add in the code for more and different ads, you should be able to at least fix long running problems with game play. If nothing else you might even be able to make more off the ads if you fixed it because the rating would then go up and more people would play. ### 1/5 — Used to be great *2016-11-09* Now some completely unrelated "mini-game" wants to load before each level. Wish there were a way to undo updates. ### 1/5 — Joke *2015-09-27* I paid for this app and i still get spammed with ads and then the app crashes all of the time . Its a shame there more worried about money than a good app ### 1/5 — Deleted after 30 seconds *2015-08-29* No in game instructions and shallow game mechanics. ### 1/5 — Amazing concept, great graphics, buggy game and ads! *2015-08-18* The game is basically structured to force you to watch adverts. All the time. Almost as much as you're watching the game screen. The hit boxes of the zombies are skewed and instead of squishing them 99% of the time you 'blow them away' off the screen where you can't see them and they are still considered alive and thus mission fail. ### 1/5 — Ads, in an app I paid for? *2015-07-26* I paid for this app and never had to see a single ad. Now, after coming back to it after a while I find ads with every level change. Sorry, not happening loser - deleted and done. ### 4/5 — One of my favorite games. *2015-07-19* Just wish the lines were fixed. But I love this game. Have for over a year. Thanks for the cool game. ### 1/5 — What did you Doooo! *2015-07-11* The game is terrible. Last update doesn't fix my iPad screen. Too big. And the advertisements on every screen change. I'm done! Deleted game. I hate, hate, hate! Bye bye! ### 5/5 — FANTASTIC FREEBEE *2014-06-28, version 3.2* GREAT, GREAT GAME, FANTASTIC GRAPHICS. THANK YOU WONDERFUL FOLKS BEHIND THIS APP FOR A VERY NICE GIFT. ## Frequently asked questions about O is for Obliteration ### What is O is for Obliteration about?
