First of all, I’m not a pro in terms of Predator lore, so feel free to fix my mistakes and add your own opinion. I also know, that “it’s a game”, so don’t waste your time typing these words :) Let’s start.
1.(Lore): Predators are very strong (physically), they can even fight (and win the fight) against Aliens with just their cold weapon (disk, sword, combistick). 1 good hit is enough to kill a human.
(Reality): Successful predator players say: "If you want to win as a Predator, don’t fight with humans in melee. They will parry your attacks, you’ll be locked in animation and they tear you apart with their knives.
2. (Lore): Predators are silent and deadly hunters, their cloak makes them almost invisible, so it’s very hard to know that there is a Predator nearby before he attacks his victim.
(Reality): Predators make noise better than a couple of elefants, you will hear them mile away. You can even hear as they change their vision mode or using cloak. The cloak itself is a garbage, successful predators say: “Don’t use the cloak, it’s harder to detect you when you’re running without it”.
3. (Lore): Predators use trees, high above the ground they stay invisible between leaves, waiting a perfect moment to attack.
(Reality): Successful predators say: “Never ever climb on a tree! You’ll be easily detected and killed”. It’s true - on the tree you’re an easy target. You’ll be locked in animation while running/jumping, your Plasma is useless (because every god damned branch or even leaf will make your shot fail), so avoid the trees.
What did I forget, guys?
