using consumables?

They're in the power wheel.

It's silly. You actually need to pause the game to use them despite having keys in multiplayer that use consumables but do nothing in single player.

I used some ammo in the later stages of the game but I could never tell when it ran out or not.

Used the ammo powers when i played on Insanity. They can help with priming enemies for combos. There is also a talent under Tech - Auxiliary systems i believe that helps weapons prime. Think that works with the ammo aswell. Need to do more research on it when i go back to playing the game.

Those Auxiliary Systems evolutions work with expendable ammo exclusively, no? It doesn't simply grant you super-powered ammunition. It enhances your expendables.

I find that I still don't use my expendables frequently enough. I'll get very low on Life Support, and think, "This is why you equipped the expendable. Use it next time," or, "That last battle would've been easy had I used Incendiary Rounds". I will likely need to consciously cultivate the habit of using them. It's a good thing they don't occupy inventory space. I have an insane hoard of them.

Insanity is what I'm playing on. I also just came across augments from Remnants that give ammo a 25% increase with element of choice (cryo/incendiary/disruptor) which I think would be a great alternative to consumable ammo. If the aug ammo can prime, it would be perfect for me concussion shot and incinerate power.

Cryo ammo with concussion shot would be sweet as Infiltrator. Does Cryo ammo gain bonuses from the passives in Cryo Beam that help with detonation? It will after all be a Cryo Detonation. These are the things i need to know.

This was going to be my original response

I'm personally not a fan of the consumable system. The first game you imparted effects through mkds and in subsequent games through skills. Between that and power cells, it feels like Soldier type characters really have to micro-manage more than techies or biotics.

I don't know about XBox or PC, but on the PS4 you touch the touchpad and a wheel will come up showing what guns and what consumables you have.

This, I'd love to use them... on hard fights... later on.. maybe bosses...

So far I've never used em.

I said I'd use them when necessary, but after about fifteen hours, and not needing a single one, I decided to start selling them for credits (which I promptly used to by shiny models for my room).

For me I feel they're just like DAI's focus powers. Cool on paper, but completely superfluous. I wish I could disable the auto-equip though.
