Punch Entertainment has released Reign of Swords [$7.99, App Store] for the iPhone. Reign of Swords is an online multiplayer game that can also be played on your PC.
The game is described by the developers:
Engage in epic online battles with a customized army in a fantasy world of magic, steel and strategy. Build up your army by gaining troops, technology & magic through engaging campaign missions that feature fortress sieges, ambushes, stealth attacks and huge open-field clashes. Then battle your friends online! Receive in-game rewards such as new units & technology each week based on your score in a kingdom. Play on your iPhone & PC.
Reviews for the mobile version of the game for other handsets appear to be glowing. Pocketgamer's review describes the game as "fantastic":
Set in a fictitious but familiar world of knights and realms, most of the action focuses on a simple system of turns. During your go you can move each unit of troops across a two-dimensional battlefield according to their range, also unleashing their particular brand of attack on an enemy. Once you're done, the opposition has its go, and so on until a territory is taken.
Meanwhile, IGN also had high praise for the mobile version of the game describing it as "an exceptionally deep game".
The iPhone version is selling at an introductory price of $7.99 (normally $9.99) for a limited time. An off-line version of the game is also offered if you are away from an internet connection.
