BG map in spoiler. (not to scale, blank area would be much bigger with places of LOS and maybe a buff hut(leaf, or zerking, or speed buff))
This is a King of the hill style BG.
Both sides would be mirrored. It is alliance vs horde.
To capture and hold the hill in order to gain a certain number of points(like a flag in AB)
The team to reach the set points wins. Or if a team runs out of supplies because the opposing team stole them all, they lose.
Each team is provided with 2 demolishers that may be used to attack the other team, They cannot however make it up the hill, but the attack can reach over the hill to hit other demolishers or incoming opposing faction players.
There are 3 turrets on top of each sides base, these are powerful and can reach to the top of the hill, It would be key to take these out asap so your team has a better chance at capping the hill.
The key strategy in this BG would be to grab your demolisers and arm the turrets, that takes out 5 people from your team, so you have 10 left to fight.
A group of players would rush through the tunnels and steal the other teams supplies, supplies speed up the respawn time of turrets and demolishers(without any supplies, the turrets and vehicles will not respawn. Stealing their supplies will slow down their vehicle/turret respawn time and speed up yours.)
The ideal plan would be to take out the turrets and demolishers as quick as possible, once that is done, you would want to guard your supplies while capping the hill.
Once your team has capped the hill, the opposing team would have to cap it back, or go for your supplies to get more vehicles to help. Or send full force to the opposing teams supplies to steal them all and win before they cap the hill.
