Sponsored Feature: Office Hero is a tower-defense title with movable towers that features RPG elements and lots of action

If you've been an iPhone or iPad gamer for more than a few months, you'll have played a tower-defense title. The App Store is littered with them, after all. Office Hero, from developer Keyloft, is one such tower-defense title.

In Office Hero, you're tasked with helping a hard-working business man called Mike protect his office from the attacks of increasingly nasty and competitive companies who want to see him fail. In order to protect Mike's workplace, you'll have to rally together his most loyal employees (the game's towers), who all have unique skills that will help you to repel the office invaders.

Unlike in most tower-defence titles, every single tower in Office Hero can be moved freely and without penalty, which adds an extra layer of strategy on top of the gameplay you've come to expect from the genre.

If you need to move a unit, you can just pick it up and drag it to a new position. It's that simple to readjust your defenses on the fly. There's also a 'Direct Fighting mode' that allows you to step into the fray, dirty your hands a little, and directly attack your on-screen foes.

If you're really lucky, you'll stumble across some free equipment during battle that will improve your chances of success, or meet one of the game's mysterious mascot characters, who'll help you out of sticky situations. There are a total of 50 stages to complete - all of which can be attempted on three different difficulty settings. You can also compete against other players via Apple's very own Game Center network.

According to Keyloft, Office Hero Is the first tower-defense title in history to include fully movable towers. It's hardly surprising, then, that it's these unique movable towers that developer Keyloft is most proud of. The developer is also rather fond of the game's RPG elements and 'finger weapons', mind, as well as the game's cute characters and their weapons, which are items from everyday working life.

Keyloft plan to keep Office Hero fresh by releasing content updates, which will introduce - among other things - new levels, characters, and weapons. The developer is even planning to add new stories and completely new game modes to the mix. You can download Office Hero from the App Store for your iPad right now. If you don't have an Apple-branded tablet, fear not: Office Hero will be released on iPhone, Android, and Windows Phone sometime in the future, too. Office Hero is available as a free download, but you can spend some real-world cash on optional in-app purchases if your bank balance is a little higher than you'd like.
