Sigh. This was quite difficult to read. It's confusing. It lacks cohesiveness. The main characters (Galen, Burke, VIrdon, Zaius, and Urko) are way out of character. Too many loose ends. Too many unexplained occurences.

I would suggest the following:

1) Take a couple of courses in Creative Writing.
2) Learn to use a spellchecker.
3) Learn to use punctuation properly.
4) Install Grammarly (it's a grammar checker that integrates seamlessly with MS Office products.)
5) Join a couple of online writers' groups.
6) Read. Read. Read. As much as you can about your subject matter. This will help you to understand your characters' mindsets and how they might react in any given circumstances.
7) When writing, create an outline-it helps to organize your story.
8) When writing fan fiction, it helps to stick to canon as much as possible.
9) Proofread. Proofread. Proofread. BEFORE publishing your story.

As for this fanfic:
1) The story/plot lacks "flow"-it jumps from place-to-place without warning. Half-of-the-time I didn't realize that it had bounced to another location. So I had to go back and reread-in some cases, a couple of times.

2) Be mindful of your words within a sentence, within a paragraph, within a section. Case-in-point: "...yawned the big blond man as he gently lay BACK on his BACK..." Awkward!

3) Related to (2) above... What's with all the "Burke, Virdon and Galen" ad nauseam? The phrase was used TWENTY-TWO times in a little over 8000 words...
"Burke, Virdon and Galen all moved switfly (misspelled by-the-way) through the dense jungle."
"Burke, Virdon and Galen were suddenly all woken up..." (check your grammar)
"Burke, Virdon and Galen just ran stealthily..." (um, someone moving stealthily is moving in a cautious and surreptitious manner, so as not to be seen or heard. They're not going to be running.)
"Burke, Virdon and Galen all moved at a wolf trot through the dense jungle." Wolf trot. Had to look that one up. Wolves trot at 5 mph but can run in short bursts up to 35 mph. Humans in good athletic form can run 28 mph for much longer periods of time. It's all moot because you're not going to be able to run through dense jungle that fast. Mother Nature places too many obstacles in your way-low-lying tree branches; gnarly roots; uneven ground around the roots; decomposing stumps; slippery footing atop years and years of detritus from decomposing stumps, leaves, branches, bark, animal skins and skeletons; trees growing too close together competing for what little sunlight isn't blocked by the foliage overhead; wild animals; animal traps set by humans or apes; and the list goes on...

4) I can't wrap my mind around "...fifteen gigantic canals dug into the jungle floor." Who bothered to count? And if the canals were that gigantic, how were any of the guys able to see that there were that many canals?

5) Urko has a wife. Her name is "Elta". He mentioned her while he and Burke were buried in the ancient BART subway tunnel in "The Trap".

6) Chapter ONE. "Burke, Virdon and Galen" wake up to the sounds of Urko and his troopers surrounding them in the jungle. The trio is spotted as they run...through the (dense) jungle. Chased by gorillas. Apparently the trio got away because the fourth paragraph states: "It was dawn. The two astronauts and the chimpanzee lay on their backs in the jungle fast asleep." I doubt they would risk sleeping until they knew for certain that they had indeed outrun the troopers. And they would likely take shifts through the night staying awake so as to warn the other two in case any gorilla or wild animal stumbled upon them.

7) How did Urko get back to Central City so quickly? He's back there by dawn? If the jungle is that close to Central City, wouldn't the apes have discovered the mutants and their gigantic canals decades earlier?

8) Zaius in the first two movies had the title of DOCTOR. Zaius in the TV series had the title of COUNCILOR (which is not the same as COUNSELOR).

There's so much more that I could add to the above. But it's late and I'm tired.
None of the above was meant to criticize-it was only meant to be a lengthy critique.
Good luck with your further endeavors.

I love Roddy McDowell. Damn fine actor and spending all that time in that make-up, what a trouper. He was in another time series around that time called Fantastic Voyage (I think) where he played a Dr. Smith(ish) character. Cheese all the way. Thanks for the read:)
