I can't wait to not shoot that giant techno-worm with my Nomad.

Real Spectres run up and melee them to death.

Guys, guys...

It's the new "art".

Is that a shard I see up on the top of the octagon shaped pillar rock formation?

Because we're peaceful explorers and heavy weaponry is problematic.

a giant robot worm

I wonder why someone would build something like that.

You do realize the melee combat is very limited in the game with only one animation per weapon like ME3, right?  

That's not entirely accurate. ME3 had heavy melee or a three strike light melee combo for some weapons.

I need to go look this up.  I thought you could only press/ hold the melee button for either the omni blade or biotic amp/punch.  I never played multiplayer though.

I also don't think we will see any enemy vehicles while exploring which doesn't make a ton of sense. It would have been nice to take a page from the Mad Max game that came out fairly recently. You have various weapons on the Nomad, but there are also other vehicles that say belong to the Kett that try to take you out. Even Borderlands and Arkham Knight did it well. It just seems lazy

If you're one of those people who only cares about top efficiency rather than fun, then sure. I had a lot of fun killing enemies on foot. Find a nice hill, park mako and snipe the whole outpost. Feels good, immersive and fun. After all, isn't this suppose to be an rpg game?
You can also build yourself to kill any enemy with only your fists in Fallout4, but that doesn't mean you have to do it. As one example. Most of rpgs have OP builds that people come up with. Or way to cheese through fights. Or power leveling. Or speed running.
Ever played Borderlands 2? You have 2 different weapons on your vehicle and you're still not OP, plus you get less experience killing stuff with vehicle, which was also a thing in ME1. Also, enemies could have heavy weaponry to deal with nomad - missile launchers, grenades, mines etc. They could also have their vehicles. Lot of ways to fix the issue, if developers would bother.

It's a Ceph Tripod for me.

But let's be a little more serious and reiterate something that apparently has already been forgotten: the fact that, at the start of the game, both Nomand and Tempest are weapon less, doesn’t make much sense.
But, let’s say we were forced to depart, destination Andromeda, ahead of schedule: reason? Unknown for now. This could explain why the main vehicles of the human pathfinder team are weapon less: there wasn’t enough time to install them. It’s silly, it’s weak as reasons go, but it can be explained.

The fact that both the Nomad and the Tempest stay weapon less, especially considering the dire reception in Andromeda, is plainly wrong. And it’s doubly so considering how little is needed (know how wise) to solve this problem. From the basic coaxial 155mm, to the more exotic remnant pulse weapons, it seems very little should be required to equip some talons and fangs to our soon to be loved six wheels chariot. In the last trailer against the ceph tripod, we see Ryder using the Kett equivalent of a minigun: why bothering struggling against its weight on foot, when you could strap it that much more effectively on the roof of the Nomad?
And for the Tempest? GARDIAN laser systems should be the mandatory base level to begin with. You know… at least to incinerate the smaller asteroids when we dive in space.
Let’s add some disruptor torpedoes, and attach their launch platforms on the Tempest flanks: 3 for side are all that seems necessary to cover that need, and to earn enough time to go FTL. And for planetary bombardment? I would be satisfied with the beauty of kinetic bombardment concept: a tungsten rod of 300 kilos dropped from orbit, for instance. With a very primitive system to correct course during the fall, 300 kilos of needle shaped tungsten, hitting at terminal velocity, would impale even our Ceph Tripod with zero collateral damage to the surroundings. And this is a concept older than the Cold War: calculating the kinetic energy of such a thing at a time, earned them the moniker of “Gods’ Rod”.

So, this weapon less state is a precise choice by game design, to cover the fact that… well, they didn’t know how to manage vehicle combat in a satisfactory way. Laziness, or the desire of not watering the game with half assed combat?
We will know in 14 days, I suppose.
