Pick Off Enemies From a Distance
While your sword is great for taking an enemy out quickly, your gun is incredibly useful when dealing with multiple enemies. With a number of different guns at your disposal, choosing the right one for the job and using them effectively will make a significant impact on how effective you are in combat. If you find yourself stuck in a room full of enemies, use one of your long-range guns to try and take a couple of enemies out from a distance.
Creep into the side of the screen, unload a couple of rounds, and then jump in and slash a couple of enemies to recharge your gun’s ammo. Then, jump back out and rinse repeat. Picking enemies off from a distance makes large groups much more manageable and can even help you take out pesky enemies with ranged weapons. Think about what you’re doing, rather than just going nuts.
