Go to cover, wait until enemy pops up or moves... shoot them. Win. Yeah, the AI could be improved.
Mass Effect never was hard when it came to combat. Only issue came from being swamped or how much actual damage an enemy does in the hardest difficulty. (Never got past Horizon on ME2 on Insanity, did that import already leveled character on ME3 so did that easily.)
Hmm, pie.
