That's not the first map I make, not even the second but probably the first I'll upload, so I would prefer ask if it could be a cool map.
The map is called "Ultimate Bro Form I - Predator Came to Life" and here are the levels :

Level 1 : In this map, we play Predator, without any dash, running for his life (a weird buiolding is exploding behind him), and Satan suggests him to give his soul and Satan will save him from the explosion. Predator accept and run into a Portal
Level 2 : In Hell (overcast). At the end of the level, Satan (PureEvil) say it's a trap and Predator fall in a cage. Then, Satan say remember how you born and there is a "Flash Back"
Level 3 : We see scientist making a new experiment, and Predator come to life. Then we play Predator in a Mook Lab-Bunker. We need to activate switches to continue and fight Mooks (especially Jetpack and Armored Mook) and activate the Destruction Button. Then Predator Run. End of the "Flash Back"
Level 4 : Satan Laugh and let him fall into a cave with what he call an "Horror Master" (in fact, that's the Humongocrawler, here Aliens are Horrors). Then, a Cyborg (GR-666) come from heaven and shoot the Humongocrowler (it crawl out of the Map), then give to Predator special ammo (there is new ammos, he got the one which do fall a Freedom Armor). In the level (Hell - Overcast), Predator continue to try to escape down and, at the end, see the Corrupted Heart of Hell (the heart of the hive). This heart (with a lot of Hp) make fire laser beam and spawn Horrors and undeads. When it dies, Preator fall with the Heart
Level 5 : Hell, night. Lots of Lost souls (skulls) and traps. I would try to make a tense atmosphere, with the Alien Music. There is no Boss, but a Tower Defense-like, with undeads and horrors. When it finished, the camera is no longer locked and there is a Zipline to finish the level.
Level 6 : Hell, BurningJungle. Lots of Necromancers, Hell cages and Fire Dragons. At the end, you see Satan which stops you and spawn a Worm. When Predator defeat it, Satan laugh and spawn a Bone Worm, and when this Worm is defeated, Satan Teleport you at "the top of Hell"
Level 7 : Hell, overcast. Mooks are in Hell and are trying to survive. In the Stronghold, there is the first Satan Boss. Then, we quit the level
Level 8 : Hell, night. Final Satan Boss fight. When it dies, Predator enter in his mind
Level 9 : A jump map, with flesh with lots of fire trap. There is a PureEvil trying to escape. When it dies, this is the end of the level and the map

Well, thanks if you read it, and I just ask what is cool and what is sh*t. If you have any suggest or question, I'll be happy to answer
