A note from Origin8 Technologies, the maker of Sentinel: Origin8 are pleased to announce that Sentinel version 1.4 is now live. This update provides a pack of new content and features for the acclaimed iPhone sci fi Tower Defense game. To celebrate this release, Sentinel is on sale for a limited period at just 99¢. Grab it while it’s hot!

As commander of the dropship Sentinel, you were first to respond to invasion from the stars. Your mission on Mars may be coming to an end, but the implacable aliens aren’t beaten yet…

Key version 1.4 features:

A challenging and graphically dazzling new map, Last Stand. Defend your escape shuttle from the vicious hordes as you evacuate the Martian colony!
A new tower and alien attack unit, each with a fresh set of powers and far-reaching tactical implications.
A new destructible building that you’ll really want to keep standing.
Improved drones that can be commanded to concentrate on harvesting or repair.
More powerful top tier upgrades for some towers.
Optional atmospheric in-game music.
Revamped game balance: ‘Easy’ and ‘Medium’ modes are now more forgiving, while hardcore players will find ‘Hard’ and ‘Psycho’ tougher than ever.
