New equipment is purchased with Blue Energon and Green Energon packs obtained during missions. Use Energon shards collected from battles to upgrade the equipment you own. Upgrading ranged or melee attacks will increase their power, while upgrading your armor will increase your hit points and allow more damage to be taken. Sell outclassed items to get Crystals for future upgrades. Focus first on upgrades for your ranged weapon. Killing your enemies from a distance is very helpful. Although ranged attacks are not as powerful as melee attacks, they are lower risk. After getting a decent upgrade with your ranged attack, consider upgrading your melee attack upgrade, and then a health upgrade. When a new Transformer becomes available, you do not need to spend anything on new equipment. You can unequip existing upgraded equipment and transfer it to the new Transformer. Sell equipment that you do not need, then use the Energon Shards to upgrade the gear you can use. Each mission has three different objectives. For every mission objective completed, you will earn a star. Stars may be combined with your Autobots to unlock and upgrade them. When an Autobot is upgraded, its stats will go up and their max level will be increased. Some Autobots require special items for upgrading in addition to Stars. Collect these items by completing certain mission objectives.
