My strategy against this boss is as follows :cham0mile wrote:The Recca stage 2 boss gives me more trouble then the other stages.
-I position myself at the bottom of the screen, in the middle, and I stop shooting. The two arms are less likely to hit me in this place and the shield absorbs the bullets.
-As soon as I see that the arms are retracting into the boss, I rush into the core and if the boss sends its arms at my location in a straight line , I unleash the bomb attack, and then use my main and sub weapon for extra damage. If the arms unfold in a rotating way, I refrain from moving all the way up, and go back to the starting position and wait for another opportunity.
-After I damaged the boss, I go back to my position to avoid getting killed by the arms.
-Rinse and repeat until the boss dies. It should not take too long.
Otherwise, you can also try this speed-kill strategy that looks riskier but ends the fight in a few seconds.
