I continue to advance through Sin and Punishment: Successor of the Skies.
This time it's the water tunnel, it's cool & large, lots of space and water there, some enemies are even surfing through it.
Basically anything small is taking out by a regular shot & anything big or armoured with a charged blast.
There were also Big eels that were making surprise attacks, just evaded them.
I figured out that I can Destroy these eels with a charged blast, no point avoiding them after that.
Defeated two commanders before saving & exiting the game, the game said I will restart at 0 points next time, oh well, whatever.
Now... We started with the bright tunnel near the surface, and since then were going deeper, deeper and deeper.
And it got darker, everything isn't clearly visible anymore.
Gotta aim at anything that moves, or glows, it will be easier this way, probably...
