Refinery Rumble is a 4 player Yellow Zone map. It was my 2nd multiplayer map for KW and it was designed back in 2013.
Each player has a single Green Tiberium field for initial harvesting. Tiberium Spikes are located near the destroyed residential areas (2x Spikes per residential area). Defensive Turrets are located near the center along with 2 EMP Control Centers.
A total of 4 small Green Tiberium fields can also be found from there, and players will fight over them eventually, once their initial supply of Tiberium runs out.
