According to previous information, in the upcoming online action game Anthem, you should be able to improve both your hero and the Javelin suit through skill trees. However, this information was incorrect; only freelancers have such skill trees. In Anthem, Javelins will depend entirely on gear – there are even set bonuses.

Skill trees only for freelancers, not for Javelins
The freelancer improves. As you may know from other RPGs, it is possible to upgrade your hero in Anthem using a skill tree. During the missions, you gain experience points that allow you to improve skills or learn new ones.
In this way, you will become better at handling the Javelin suits, become a more effective pilot, and utilize the suit’s abilities to defeat tougher opponents.
The Javelin does not have a skill tree. Even though it was previously stated that you could even upgrade the Javelin suits via a skill tree, according to BioWare’s Mark Darrah, this is misinformation.
What is true: A Javelin can be upgraded. It is therefore possible to equip new gear that makes the suit more powerful. Javelins do not have a separate skill tree. The level of your freelancer is also responsible for how powerful the loot you find is.
There are set bonuses
Find set items for bonuses. Since loot plays an important role in Anthem, you will frequently find better upgrades for your suits. This includes set items. Mark Darrah from BioWare has not yet spoken about how exactly this system works.
He only confirmed that there are sets. Presumably, this will work similarly to MMORPGs or Diablo 3, where you find certain compatible upgrades for the Javelin that unlock a bonus when assembled in a set.
One will need PS Plus or Xbox Live for Anthem
Will you need PS Plus or Xbox Live to play Anthem online? Darrah also answered this question over the weekend: Yes, you will need these paid services if you want to play with others in Anthem on PS4 or Xbox One.
Anthem will launch on February 22 for PC, PS4, and Xbox One. Every player starts with the Ranger as their Javelin.
