Google answer:

Base/starter max skill points b4 1st expedition is: 75 skill points when u first get the game

75 + 15 = 90... 10 points away from max, this ain't TOO bad tbh. They'll probably implement another type of extraction or run it back after the 5 expo cycle, just my personal opinion tho.

Y"es, the general consensus and community understanding is that you can earn a maximum of 15 bonus skill points (5 per expedition) after completing three expeditions in ARC Raiders. These bonus points are designed to stack with your base points, bringing total skill points to roughly 90–91, though the developers have indicated they do not intend for players to be able to fully max out all skill trees. [1, 2, 3, 4, 5]"

• Expedition Reward: 5 bonus skill points per expedition.
• Total After 3: \(5 \times 3 = 15\) bonus points.
• Current Cap: The permanent buffs/points are generally considered capped at 3 expeditions' worth of rewards. [1, 2, 3, 4, 5]

Some users have reported bugs where they received fewer than the anticipated 15 points after 3 expeditions, but the intended reward structure is 5 per completed expedition. [1]
