Just a couple days ago, Big Huge Games and Nexon M released a brand new DomiNations trailer (embedded below) celebrating the launch of Oil Boom, the latest update in the mobile strategy combat game. The Oil Boom update comes packed with the addition of Oil, a new resource for players to mine and collect, as well as new powerful offensive units which can be purchased with the treasured black gold.

Here’s the full list of what the recent update includes:

• Discover Oil – Beginning in the Enlightenment Age, players can build Wells and Refineries to collect and store oil and use the resource to buy tactical new units.
• Gatling Guns – This new offensive unit creates a wall of lead that can cut through large groups of defenders and pave the way for the rest of the invading army.
• Guerrillas – Undetectable by enemy towers, this new unit can sneak through gates and plant explosive to clear out enemy defenses but attackers beware, enemy defenders can seek them out on foot and destroy them with ease.
• Attack Efficiency – The latest update also brings a series of fixes including better troop movement, focused fire and targeting.
