As with most regions in the universe, the Alimbic Cluster isn't without a myriad of doors and hatches sealing areas and blocking access to deeper regions.
All the hatches you'll encounter have a way to bypass, with most simply requiring the correct weapon to do the job. Read on for a list of all the obstacles you'll discover along the way.
Doors, hatches and force fields exist to prevent Samus from accessing deeper, more secure regions of the Alimbic Order's territories. Most simply require the right weapon to disable the technology. For force fields, you'll need to shoot the guard node moving about on it with the right weapon to power it down - using the wrong weaponry results in the node sending a shot back at you.
