Kayeka for your guide: "squidform" is not a word. Either separate the two or add a hyphen between them. "All in all, a very versatile weapon." is not a complete sentence. I'd suggest adding the actual subject to it which In this case would be Splat Bombs.
“Yeah, that kinda game.” is another fragment. You’re missing the subject again. “The suction bomb function much like the Splat Bomb.” Add an “s” to function. “The trade-off for this, is that the Suction bomb will stick to the first surface it touches.” Remove the comma.
“A nice sub-weapon for the more aggressively-minded player, trading bunker-busting for direct firepower.” is another incomplete sentence. Guess what’s missing.
“Once released, your little robot buddy wil home in on the target, and explode on contact, splatting your victim.” Will is miss-spelt. “A very interesting tool in any team’s arsenal.” is yet another fragment. The same part is missing.
“Opponents can not shoot through it, but you can, giving you a distinct advantage.” Cannot is one word, not two.
“For a certain definition of “even”, of course.” is yet another fragment. This is your most common mistake and this isn’t the last one. You cannot simply assume the subject of one sentence because it is in a prior one. That’s not how it works.
“Uses little ink, so there’s no reason not to start off all firefights with this.” Look at that. Now using just that sentence, what exactly uses little ink? You can’t say. Fix it. “Loaded with ink.” I’d suggest combining this fragment with the previous sentence in your guide to make it a complete one.
“Fire powerful tiny tornadoes that travel very far and reach really high.” Not only this missing the subject, but with one included it should be fires not fire.
“A pretty scary prospect.” ”A potent weapon to take care of multiple spread-out foes.” Take a wild guess what these two fragments are missing.
“As such, you can not expect to get splats with this, unless the opponent is completely cornered and you’re just stylin’.” You know the drill; cannot is one word, not two.
“A small price to pay for such a great option in flushing enemies out of cover.” I wasn’t kidding when I said this is your most common mistake. A sentence must be able to stand on its own as a complete thought or it’s only a fragment at best. In order to properly get your point across to the reader, you cannot leave out any vital information.
“Another great bunker-busting option.” “A nice, straightforward, and pretty spectacular fire-and-forget weapon.” What exactly are the subjects of these two examples? That’s right. They don’t have subjects.
“Your opponent will have no choice but to run away or find themselves pasted over the floor.” “Opponent” is singular. “Themselves” is plural. Either add in “s” to opponent or change themselves to just them.
“Think of it: how havock could you wreck with an entire team that’s invulnerable for a few seconds?” Add the word "much" between how and havock which incidentally should be havoc.
"A weapon which main advantage is being pretty darn scary." Just read this. Slowly.
"Other than that, not particularly impressive." This is like a running joke for you. What's not particularity impressive? The reader should know just by reading that sentence. Stop neglecting the subject! It's vital to the reader's comprehension!
“Doesn’t look very good on your youtube channel, but this is the sort of thing that might just help take the game.” I’m just going to bang my head against this wall over here. Don’t mind me.
