1 - starting area
2 - destination (destroyed village)
Ignore the fact that large explosions are taking place in the vicinity, because you'll be safe here. You won't have to hide nor use your weapon. Notice that a second VTOL has crash landed in the area (screen). Once you're ready to get moving, start following some of your colleagues. Notice that you'll receive a lot of hints along the way. You'll find out more about how to control your character.
You should be heading north-east. Use my map if you're having some difficulties finding a correct route to your destination. Thankfully, you can't get lost, because there's a large canyon here and you can't leave it. Eventually you'll come across a small opening (screen). You must press and hold CTRL key here to crouch. You could also lay down on the ground by pressing the Z key, but it won't be necessary. Get to the other side.
Eventually you'll get to a destroyed VTOL, but you may as well ignore it, because you won't have to rescue anyone. Avoid a new obstacle by pressing the SPACE key. This will allow you to perform a standard jump. Turn east and proceed towards the rocks (screen). You'll have to use your nanosuit for the first time. Activate the menu and choose maximum strength feature. Press the SPACE key and you should end up standing on the upper level. Head on to a destroyed village where you'll presented with a new cut-scene.
