This, sir, is not a story in the way we define it. It's more of a...script or a screenplay than anything else. Either way, I'll do my best to edit this. Now I'm unsure as to whether knights in RuneScape times would even know such swear words like what Sevlen said.
QUOTE
sir we must get ready for war!
You're capitalizing 'Sir' as it's a title, a rank given to someone. You haven't done this throughout the script as I'm going to call it.
QUOTE
Goblins Sir - they want to overthrow humans!
You were missing any punctuation there.
QUOTE
Ready for Battle!
You don't need to capitalize this phrase, it's fine as...
QUOTE
Captain Ark: Very well, get every Warrior ready for battle!
QUOTE
Get your sword and shield. We are at war with the goblins!
Capitalize and punctuate!
QUOTE
Warrior James: Ouch! The 1st is always the most hard!
Never - put things like 1st, 2nd, 3rd into your story or script unless you're making a list of something. Otherwise, type it as a full word. First, Second, Third. It's much more presentable and looks better in a writing piece.
QUOTE
Warrior Renie: 50%50 you will die in this battle!
I believe it's 50 - 50. Now with that too, don't type numbers in your story unless they go above one hundred (I think that's the number...). Otherwise, do the same as above, type it all out. One, Two, Three.
QUOTE
Warrior Henry: HEY I SEE E'M!
Captian Ark: GET READY TO FIGHT!!
Capitalizing full sentences rarely, if not never, works. It throws the reader off and isn't very presentable, standing out like that. If you want to emphasize a point, add exclamation marks or bold one or two words. Don't underline though.

"Gulp"
If this were a story, he wouldn't be saying 'gulp'. You'd have to explain it through a sentence such as:
Sevlen gulped.Of course less primitive and basic like that, you elaborate on it.
However it is a script/screenplay, so, you put '[ and ]' (I think...) on both ends to signify that it's an action as such.
I can't exactly compare this to any other of your works seeing as it doesn't even fall in the same category. Practice, practice, practice my friend. Take people's suggestions and advice, apply them! Don't stray too far out of the box as to do things like these (although they are good fun once in a while). You have potential waiting to be unlocked - so aim for it!
Good Luck in the future, Life.
