Okay so the most important part of this is to practice all the way from easy and work your way up to impossible BUT you must be certain you can even beat the 2nd last lvl on easy then you go on to normal then hard then impossible! This topic was mainly for people who are struggling with impossible but also know how to kill the AI easily on impossible so if your one of those players you came to the right place because I am about to tell you the MOST IMPORTANT tips to beat impossible!
Grenade bouncing!
Simple stuff! Bounce a grenade off a wall in front of you aiming upwards to hit an AI on the platform above you!
Grenade launching!
Simple! Slow down and throw a grenade then shoot it in the direction you threw it! It should give you a second or two to re-plan your engagement with the AI!
Calculating (yes that is actually a thing I do that helps A BUNCH)!
You must calculate the places grenades you want them to go. For example. A enemy is on the platform above you but you do not know how high or low you have to aim to get him so you imagine pixels and calculate with them. Here is how it should look
2 + 3.5 = 5.5
That is how I calculate it to make it simple but if you want to bounce a grenade off walls it will look something like this
3 + 3 - 2 + 3 + 6 = 13
Yes it gets very long! So, estimate the landing if it gets THAT long
Slow movement!
Simple! Look around at all times and keep track of every enemy that could and might attack you and always be ready for an attack from any direction!
Advanced grenade bouncing!
Bounce it off of 4 walls or so to hit an enemy in front of his ally without killing your ally at the back! Now that goes back to the calculation part I was talking about!
Advanced grenade launching!
Launch a grenade and wait a few sec (make sure it's in slow mo) and then shoot the grenade when it has passed/hit the target and/or wall and watch your enemies go BOOM!
Easy Parkour!
Simple! Jump from one ledge to the other in ragdoll mode (going back to the calculating part and calculating your landing if you can or have the time) and don't damage yourself too much upon the landing!
Advanced Parkour!
Wall jump from one wall to the other then get to your destination and slow mo and jump from ledge to ledge passing your foes! You can take any route you want but I don't recommend that in the impossible mode since the enemies are basically super-enhanced-humanoids
Hardcore Parkour
Jump from ledge to ledge shoot your enemies pass them ragdoll, dock, weave, shoot and run like lightning through the level blasting pass your foes! The method I like using most of the time!
Truth...
Practice from the easiest techniques in this guide and work your way up like how my guns work their way into the AI's faces! Wait what your lazy? Too bad bud! You won't be learning the hardcore parkour or even the advanced if your so lazy and if not good for you... Now, PRACTICE!
And that's all you need to know! Goodluck making the AI poop bricks from how awesome I made you! If this didn't help you then keep it to yourself! Don't be a butt face!
