There's also a "Narrative" mode that does something about combat, I believe. I forget what exactly, but I'm pretty sure the entire purpose of Narrative mode is to make combat a non-problem for those who don't want to bother with it.
And to expand on Teneb and powers:
You can have up to 4 (or more?) favorite slots at a time, each with its own set of active abilities - any unlocked passive abilities are always in effect, I think?
Even though there are a lot of different abilities and each ability can have a lot of points invested into it, the speed of leveling up combined with the lack of a level cap mean that being able to branch out into different abilities is very possible.
Each slot can have an assigned "Profile", which is similar to a class from the OT. These profiles - Sentinel, Vanguard, Soldier, Adept, Engineer, etc. - each have a hefty set of bonuses corresponding to their role and usually some cool things too. For example, the "Explorer" profile (a jack of all trades for Combat, Bionics, and Tech) gets a special dash which is essentially a "Blink" that lets them go through objects. The Vanguard profile allows you to get shield back from melee.
Profiles are easily unlocked by investing points into their corresponding sets of abilities.
The powers themselves are all great in Andromeda, in my opinion. Even stuff like the Charge ability are better thanks to the jump pack, allowing you to do cool stuff like jumping up then charging at an enemy in cover. My current favorite set of abilities is Charge, Flamethrower, and Backlash. So I can charge up to a group of enemies, flamethrower all of them, then repeat. In case of emergency situations, I can use backlash which is basically like a "held" directional shield that reflects projectiles at your crosshair.
