In the Prelude Third level (Double Down) there is a rock wall that I cannot pass through.
When I touch it an 'insufficient firepower' "error" appears on the screen.
How do I get past this point?

This Video shows the player using a shotgun to blow down the wall. The right click option for the shotgun should fire an explosive:
Press 'Right Mouse Button' to fire an explosive.
They appear to have obtained the shotgun just prior to this by taking down the boss in its first phase.
1The game will teach you this later, when you get the shotgun (5-10 minutes from this wall, I think? Don't really remember), but essentially: cracked walls can only be blown open by the shotgun's secondary fire (be it the default launcher mod or the pump mod; although you need to punch the bullets when doing this with the pump mod).
