About this app
Robo Defense is the ultimate portable tower defense experience. Featuring open maps, upgrades, achievements and nice graphics.
The full version features 5 maps with unlimited upgrades and difficulty levels.
A free version is also available (try it first!).
Free version progress is automatically imported into the full version, should you choose to upgrade.
HTC Desire, San Francisco: Turning off "High Quality Graphics" fixes known issues.
Galaxy S: Turn on "16-bit Backgrounds" to fix studdering performance issues.
Atrix: Disable sound to improve stability
Performance tips: If the game is running sluggishly, try playing fully "zoomed in". Turning off "High Quality Graphics Mode", in the options menu, will also help on some phone models.

Evidence and review signals
This is where the page changes from an app-store listing into an evidence report: findings, important reviews, pricing and a dated history.

Themes reported by reviewers
No theme reported
Counted from the reviews we have read for this app. "No theme reported" means no theme reached our reporting threshold — it is not a finding that nothing is wrong with this app, and we do not say it is.
Five-star share of ratings
Under 65% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
