I am on one of the first levels of NOVA 2, where I entered in a factory, and jumped in a Mech. I am then taken in a room where I have to destroy six tanks, and four Mechs; from there, I have to go in another room, but the Mech doesn't pass through the door. I tried finding another path to reach the point I should reach, but the only way seems to be passing through that door. I cannot jump off the Mech, as the "E" key doesn't seem to have any effect (and I didn't set another key instead of "E").
There are five other doors, but I can use just three of them. I was able to pass through two doors, but they take me to a room without other doors; the remaining doors are the one to which I am directed, and the one that faces on the ocean, which is blocked.
How can I pass through that door? I also tried side-walking but that didn't help.
The main objective reported is the following one:
Get into the courtyard and clean out any resistance.
The log reports the following sentence:
There is heavy resistance amassed outside. I would hold on to that Mech.
