"That’s what happens when you don’t bring protection. Idiots."
"What do you mean, ‘protection?’"
During development of Mass Effect 1, Noveria’s Aleutsk Valley had several encounters and enemies that were eventually left on the cutting room floor. Here’s another one where I’ve spliced the leftover audio files together.
After defeating a group of hostile krogan in the valley, Shepard comments on how lethargic they seemed. Wrex explains that krogan feel the cold more intensely than other races, and has a final request to get out of the weather (which is an ambient comment not directly tied to the conversation).
Every squadmate has recorded lines for this encounter. It was probably intended to be a short cut-scene with dialogue options.
