Tuchanka Reaper – Mass Effect 3
It’s hard to describe the sheer awesomeness that surrounds the entire fight around the Reaper on Tuchanka. Not only do three races band together to take down one of the baddest enemies in the universe, but they also call upon the mother of all Thresher Maws to finish it off.
Everything suddenly turns into a giant Godzilla-esque fight that you simply get to watch and enjoy from a very dangerous position.
Honestly, the Reaper fight on Rannoch gets pretty close to this fight in badass-ness especially since it’s just Commander Shepard vs. a shrieking, intimidating enemy.
However, so much more is added to the Tuchanka fight with the alliance between the Turians and Krogans, the crazy run between the Reaper’s legs, and the fantastic battle between the Reaper and big mama Thresher Maw.
