So, here I am to give the idea of putting several spawns on the HUD of the OW, that would give you the ability to certain things to any part of a map. Such as burying rollermines, concealing a poison headcrab, or dispersing manhacks. But it wouldn't stop with summoning an ambush. You could fire a dummy headcrab canister, roll a flaming barrel off a ledge, even target an area with the Suppresion Device. (Not to be confused with the suppresion field.)
Each ability can be customized for your map by placing a brushes on it that would dictate what open space needs to be around it, or even brushes on the map that would dictate exactly where it can or cannot be used. There could also be a toggle, so at the mappers discretion you can choose whether it can be used within the sight of the Rebels or not.
Some examples of how it could be transferred to the current maps:
- The flaming barrels on the first part of OW_Canals can be given a longer timer than their set counterparts, then they can be spawned on part of the canal lips in the first part, where they are then spawned lit and pushed into the canals by pushes placed on spawn areas. Frequency scales with number of Rebels.
- On the final area of the Canals, part of the OW's setup can be to place one or two groups of burrowed Rollermines for the finale. Add one rollermine for every two rebels, with one rebel meaning one mine.
- During OW_Breach, you could spawn a few manhacks (much less than current spawns) in areas that they normally aren't spawned-in. This would follow the same pattern as the Canals Rollermines.
- Also in Breach, you could spawn 1 Stunstick Metrocop to ambush the Rebels wherever you wish it to.
- In OW_Crossroads, you could spawn an inexplicable Poison headcrab where the Rebels cannot currently see it every once in a while. The frequency increases with number of Rebels.
