Set in a world up in the sky, in Portal Quest players first take control of up five characters at a time, with a maximum of 20 to choose from. Each has unique skills and abilities which are required for different scenarios: Elder Mohawk will fight on the front line and so is strong but vulnerable, meaning it’s useful to keep Rogue Bowman, an archer, at the back for cover. With heroes ranging from hex witches to werewolves, you have a lot of different attributes to try and tactically fit into a small team.

Only three are available at the start, however, and in order to unlock the other characters you need to progress further through the story. The campaign is split into several different areas, and within these stages of varying difficulty. At first the battles won’t seem challenging at all, but as you make your way through the map the bosses and their minions improve in health and strength. Luckily after every win you’re rewarded with loot, coins, and experience points: loot can be distributed amongst your team to improve their stats, whereas coins and experience points are used to directly upgrade your heroes.

If you want to move away from the campaign there are many separate things for you to do in Portal Quest’s world. Once you reach certain levels Crusade, Trials, Fortress and Tower offer different game modes, whilst Merchant, Guilds, Trade Ship and Dragon Shop allow you to use your in-game currency to purchase new goods. Daily Quests offer you achievements and unlocks, and Chests give you timed rewards. With so much more depth to Portal Quest than just the main storyline you’ll have enough enemies to battle and upgrades to collect to last you months of play – unless you purchase gold coins and diamonds with actual money, of course.

Portal Quest is a game for both those who like to delve deep into every part of a map, every mission, and collect every item, as well as players who want a quick round of battle against fantasy creatures.

Its characters are interesting and likeable, with dialogue even included to add a sense of depth; every hero can be improved upon with unique weaponry and skill upgrades; the world is as big as it can get on a mobile phone or tablet screen. The developer has set a marker for all other RPG apps to follow. This doesn’t mean it will only please fans of the genre, though: Portal Quest is a game for both those who like to delve deep into every part of a map, every mission, and collect every item, as well as players who want a quick round of battle against fantasy creatures. However you prefer to play your games, Portal Quest is essential.
