Lately it seems like tons of classic iOS games are getting new life with modern updates, and the latest is Critical Thought Games’ tower defense title geoDefense ($1.99). This update was announced in mid-December, and in fact it just barely beat the clock and arrived just before the end of 2014. The update adds native support for all the various iPhone screens as well as support for iOS 8, which had previously rendered the game completely broken. The update also removes OpenFeint, which died a long time ago, and replaces it with Game Center for online leaderboards.

If everything goes smoothly with this current update for geoDefense, Critical Thought will also push out a similar update for the sequel geoDefense Swarm ($1.99), so I’d expect we’ll be seeing that one in the not too distant future too. Also, both geoDefense games are set to get new level packs, which should please long-time fans. geoDefense is one of the oldest tower defense games in the App Store, and it’s still one of the best, so if you haven’t experienced it before I highly recommend checking out the newly-updated version.
