You need to jump around in the first part. When you get to the turrets and the tank crashes through the first metal gate, use rolling long jump to evade the bullets. When you get to the pylons, break the energy tanks to get past the next gate. Keep going. When the tank comes at you again, hide behind the ammo. When it destroys all of them, you have ten seconds to get to the emergency exit. If you make it, congrats.
