Benefits (How this will benefit the server and game as a whole): MAH IMMUHRSION!! This suggestion is made completely in favor and pleasure of predator players. (I'm not a predator player).
Details (Description of how you think this would work, the benefits, etc): So. How this should work.
When predator comes close to jungle wall, right-click on it, he has "Climb tree" verb. "Climbing" takes 2-3 seconds. After that, he moves ONTOP of jungle wall. Stalker and choose prey like a real predator!
While on top of jungle wall:
- Predator appears to marines and aliens, like if it had switched ON cloak. But without draining enery, just changing the sprite. RP-wise - difficult to see something high in trees, esspecially if you are not looking for it.
- Predator has special verb, that he can use only while being "on a tree" - "Jump on a tree". Works like pounce, but you can pounce only on other Jungle wall tiles in range of 4-5 tiles. Pursuit never was so immersive!
- Aliens with spits and marines with bullets can shoot at predator. If bullet hits the target, predator should "fall off" and appear on any side of jungle wall, except the side of shooter. It will should get small random leg brute.
- Predator can't use plasma caster or any other weapons, while being "On a tree". No RP reasons, just balance.
- Finally, third verb - "Jump off the tree". Jump from jungle wall at floor tile in 2 tiles range.
Implementation (Optional, if you have an idea how to implement it): Quite big amount of coding, but for some things can be used existing code, pouncing, for jumps, for example.
