On June 6th, 2014, Playdom released Marvel: Avengers Alliance Tactics, a spin-off to the popular Facebook game Marvel: Avengers Alliance. This new game is notably more complex than the original, especially in regards to upgrading heroes. In the original game, heroes could gain levels and be upgraded with ISOs. Marvel: Avengers Alliance Tactics includes all of those options and then adds a few more. Whether or not you are familiar with the original game, the following guide to upgrading heroes in Marvel: Avengers Alliance Tactics will introduce you to the combat system and help you navigate it successfully.
Advancing Levels – The most basic way to upgrade a hero is for a hero to gain a level. In order for a hero to gain a level, that hero must earn enough experience points to qualify for the level and then train to the next level. Training costs silver, Shield Points, and time and only one hero can be trained at a time. Additionally, your Training Center must be a high enough level to train the hero to the next level. When you do successfully train a hero to a new level, that character always gains increased stats, and sometimes gains new powers, ISO slots, or unlocks a new power slot.
Powers – A hero can have up to a total of six different powers. One power is always a passive power, one power is always a guard power, and the other four powers are always active attack powers. At first level, only the passive slot, guard slot, and first power slot are unlocked and the passive slot is empty. The remaining attack power slots are unlocked at level 2, 6, and 9, respectively. New powers can be bought, acquired in Shield Bonus Spins, or gained by leveling up. You can freely swap powers into the appropriate slots from the Team menu.
Upgrading Powers – Powers do not have static benefits in this game. All powers also have a level and that level can be increased by upgrading the power. Upgrading a power can cost silver, Shield Points, refined ISO, or even gold, depending on the power. Upgrading an attack power generally increases the damage the power deals. You can see the change highlighted in green when you hover your mouse over the upgrade button. A power can have a level that is as high as the hero it is equipped to.
ISOs – ISOs improve the base stats of the character by a specific percentage. For example, the Speedy ISO increases the evasion of the hero it is attached to by 4%. Heroes can have a total of 15 ISO slots, though these slots won’t all become available until the hero is level 15. You can equip an ISO that you have acquired as a reward from an Assignment or buy an ISO. You can only purchase ISOs that have been unlocked and ISOs always cost refined ISOs to purchase. To unlock new ISOs you need to increase the level of your ISO-8 Workshop.
Alternate Costumes – Heroes can also be upgraded by purchasing an alternate costume. At this point no alternate costumes are available, but Playdom has already revealed that they will be available shortly and there is a tab in the hero screen that lets you switch costumes. If you have more than one costume, both need to be equipped with powers separately.
Agents – Basic Shield agents are like heroes, in that they can be upgraded in the same way. All basic Shield agents have the same set of available powers.
