We are happy to say that the first of our planned updates to bring turn-based multiplayer using Game Center to our games is now available!
A larger update to Medici (which needs the most catching up) is still in progress.
Here's the list of what's new in Tikal 1.2:
Replaced OpenFeint with GameCenter for turn-based online multiplayer.
Up to 4 players may play online, or 2 or 3 players may play with possible AI opponents. "Undo" is also now supported in online games.
NOTE: online games now require iOS 5.0 or later.
Replaced OpenFeint with GameCenter for achievements and leaderboards.
Significant improvements to the AI.
Restored option to turn off confirmation messages.
Added "Last Moves" log.
Fixed bugs with worker/leader selection.
Fixed bug with stats that could cause loading and undo to take a long time.
Fixed bug that allowed invalid last tile placement.
