How to unlock the Combo Master achievement in R-Type Dimensions - Definitive Guide
First level, really early on.
There is a patch with a dome structure above and below you which spawns a few enemies. Take them out and anything else currently alive.
Then start charging your main beam (hold down A)
just beyond the next wall are 2 more dome shapes which will spawn about 16 enemies.
All of them will snake their way toward you through a narrow gap.
When it looks like 10 are lined up, let slip the dogs of war (fire)
You should hit 10 with ease.
Despite looking like many shots at once, it's still one shot so it'll count.
The easiest place I found to do this is on stage 1 of R-Type II. You will clear out a few enemies then have to head through a narrow passage. 2 rows of enemies will pass through the passage, charge up a shot by holding down and let it fly when they are lined up in front of you:
In R-type II you can charge a shot just like you can in R-Type, however if you charge it long enough, there will be a small window of time when the power bar flashes between orange and blue, release during this time and you will unleash a more powerful charge shot that covers a much wider area.
On the first stage of R-Type II, you will come to an opening after fighting 3 waves of red enemies and a wave of orange enemies. Through the small opening a wave of exactly 10 orange enemies will come flying at you, it might take a few tries but you want to charge up this powerful shot to coincide with most of the enemies being inside of the opening.
Too early and it will miss the last ones, too late and you will either die, or the shot will miss the first two enemies.
