A patch went live today for Metal Gear Solid 5: Phantom Pain that includes, among other things, the ability to buy insurance for your base with in-game currency either earned or purchased with real cash.

The FOB (Forward Operating Base) insurance compensates you for any materials and staff lost due to rival infiltrations during the insurance period.

"Staff/materials stolen by the rival will in fact remain on your base, and an identical amount of staff/materials will be handed over to the rival instead," according to the official description of the insurance.

The insurance is purchased with MB coins which can either be purchased with real money or earned in-game. MB coins are sold in bundles that range in price from $0.99 to $49.99.

According to NeoGaf, one-day coverage costs 50 coins, three days costs 100, a week costs 200 and two weeks costs 300 coins.

And that insurance doesn't cover the loss of:

Staff/items that are not fully your property, such as abducted staff being held in your Brig (FOB)

Wounded staff (staff lost due to death or extraction will be compensated)

Staff used by you to deploy in defense of the FOB (neither death nor extraction will be compensated)

Nuclear weapons

In The Phantom Pain's Forward Operating Base (FOB) mode, players have the option to expand their headquarters, Mother Base, by building an external base. That base is an optional, online version of Mother Base — they can only be built if you're playing online — and establishing a FOB "will complement Mother Base by funneling increased profit, resources and manpower to Diamond Dogs," your private army.

The nearly 1 GB patch also includes new combat deployment missions, new weapons and equipment, a number of smaller patches and the ability to use MB coins to speed up FOB expansion building. You can find all of the details right here.
