For some stupid reason, this was never posted to the official Mass Effect You Tube channel, so I didn't even know about it for a couple of days. I get that the see-through enemies are probably supposed to be training holograms or whatever, but they're still hard to see. I didn't really like that, but the rest of the combat looks potentially pretty good.
Here's a nice analysis video, as well as a couple of small corrections. This does contain a few more gameplay spoilers than the actual trailer, so consider yourself warned:
Hey guys, a few corrections:
1. With the holsters, it looks like we'll start the game with two holsters slots and a melee weapon slot (as showed in the pause menu in this video). The extra holsters will expand to the two empty slots on the same screen.
2. The rarity levels on gear seem to have a discrepancy between what's in the gameplay and what was reported from my sources (press that got to play 5 hours of the game.) Unless things have been changed, what we've seen so far is bronze is common, silver is uncommon, gold is rare, and N7 is ultra rare. We haven't seen a platinum so far.
Thanks to those who cleared those things up. Thanks for watching!
