Infinity Blade

Infinity Blade is an action role-playing iOS video game developed by Chair Entertainment and Epic Games released through the Apple App Store on December 9, 2010. It is the first iOS game to run on the Unreal Engine 3. Upon release it became the fastest-grossing app in the history of iOS, selling US$1.6 million in four days. It has received three major updates since its release and has been reviewed favorably by gaming critics. A sequel was announced on October 4, 2011 and was released on December 1, 2011.

The game follows a repetitive narrative structure in which the player ascends a castle in a quest to battle the primary antagonist, the immortal God King. At the beginning of the game, the player's character will be slain by the God King. The player then restarts the ascent, now assuming the role of the dead character's descendant. This cycle continues every time the player falls before the God King. As each cycle passes, the enemies increase in difficulty.

The game has no virtual joystick; movement is scripted. The player taps highlighted points to move from room to room. Inside each room the player can move the camera to search for treasure and potions.

The primary game mechanic is one-on-one sword combat with enemies encountered throughout the castle. The player controls the character's sword by swiping a finger across the screen. Players can touch the bottom left or bottom right side of the screen to dodge attacks or the bottom center of the screen to block attacks with a shield, which breaks if used too much. Finally, players may parry incoming attacks by performing an intercepting sword move. Each of these three counters leaves the enemy vulnerable to counterattack for a short period. Players may also use two special abilities, both of which require time to recharge after use. Tapping the icon on the top left unleashes the Super Attack, which stuns the opponent temporarily. Magic is activated by tapping the icon on the top right and then drawing a magical symbol. There are three types of combos. Left, right, left, or the opposite, is a Huge Hit, dealing the most damage possible in three hits. Left, left, right, right, or the opposite, is a Mega Hit which deals the most possible damage in four hits. Left, right, up down, left is an Ultra Hit, which deals the most damage possible.

In addition to combat, there is also a mild role-playing component. An experience points system levels up the player and the player's equipment, which consists of weapons, armor, shields, helms, and magic rings. Pieces of equipment have special properties and a predetermined amount of experience points required to master them. Mastering a piece of equipment increases its sale value but it decreases the experience the player receives by one fifth. Players gain points when their experience level increases or they master a piece of equipment; these points can be spent to improve the character's health, attack, shield power and magic. Players can purchase new equipment using in-game money taken from the castle or from defeated enemies.

Infinity Blade II was announced on October 4, 2011 during the Apple iPhone 4S Presentation Keynote. It was released on December 1, 2011. The sequel features enhanced graphics, a revamped storyline, along with two new weapon classes added in: Dual Wielding and Heavy Weapons, in addition to the already-existing Shield & Sword.

Infinity Blade II garnered critical acclaim from many major video game critics. IGN gave Infinity Blade II a perfect score of 10/10 and also stating that "Infinity Blade 2 is a must own". GameSpot gave the game a score of 9/10, calling it "The Perfect Sequel".
