Reviews around the Web:

The iPhone App Review (9/10) : "Sentry Alpha is a great game. Probably one of the best, if not the best, I’ve played on the iPhone. If you only had $2 to spend, I’d spend it on this."

AppCraver (9/10) : "Overall Sentry Alpha makes for an excellent game. It is highly recommended for anyone who wants some inexpensive and engaging fun."

Touch Arcade: "It’s somewhat slow paced, but the onscreen action is not sparse. It’s an enjoyable iPhone shooter."
