Bubble Defense is a tower defense game. There are several of these available on the Market and this is one of the simplest looking, if no less addictive for it.
The basic concept is to build up defense towers along a path to try to defeat wave after wave of increasingly armoured bubbles which follow that path.
There are four different kinds of towers:
- The Basic Tower – shoots a single shot
- The Six Barrel Tower – shoots 6 equally spaced shots at once
- The Flame Tower – melts ice balloons
- The Transporter – transports balloons back to the beginning of the track
These towers are used to defeat the 7 different kinds of enemy. Most of these are basically the same, with different colours and speeds, all nested in one another. Shooting each enemy removes 1 “layer” of protection until you finally get down to the last layer and destroy them. The most difficult enemy shoots back though, so be careful
You earn money for every hit but, unlike many similar games there’s no interest to be earned by saving your cash, so feel free to splash out.
There are 7 different path layouts and 5levels of difficulty, leaving quite a lot of variety and replay value.
Bubble defense is available as a free ad-supported version or as a full version for 99 cents. One thing that annoyed me after buying the full version, and is something I’ve seen in several upgrades of that kind, is that your history of high scores isn’t imported to the full version. It might be a bit of extra work but it would be rewarding for those of us who’d played enough of the free version to cough up the cash.
