Yup, it's got gunpods the game animation shows them firing in tandem, 1 from each arm.
I forget if they also work in Gerwalk mode, but they're definitely there in Destroid mode
The rail guns won't fire unless it's in Gerwalk
EDIT:
From what I remember, you can pretty much do all the acrobatic stuff like say, a VF 1, but it's pretty slow.
And the game soved the landing gear problem by simply switching to gerwalk if you get too close to the ground
