If you played Shadow of Mordor, you may remember these were opportunities to avenge the death of one of your friends by summoning the orc that killed them and fighting to the death. Both the Orc followers and Training Orders are useful for the objective of assembling an army inside the game. You'll be able to spend either Mirian or gold on them, with Mirian being an in-game currency you can earn through killing treasure orcs, destroying gear, or finding stashes in Middle Earth.

Loot Chests: Contain Gear (weapons and armour) of varying rarity. War chests reward with new Orc followers, again "of varying rarity" as well as Training Orders which can help customise the Orcs in your command. The latter is awarded in game, but can also be purchased with real money.

Bundles package up Loot Chests, War Chests and Boosts together at a great value.

The publisher claims that all content and gear in Shadow of War can be obtained without paying extra for gold to use in the Market. Silver chests can be unlocked with the easily obtainable in-game currency of Mirian.

If a player succeeds in Social Conquest, they'll get a loot chest and spoils of war, which can be redeemed for spoils of war chests.

What is Gold and how do I earn it? Gold will also occasionally be given out for certain achievements like reaching in-game milestones or participating in community challenges. It can also be purchased for real money through the PlayStation Store, Xbox Store and by adding funds to your Steam Wallet. However, I've heard "it's not pay-to-win" before, only to discover a title is actually "pay-to-not-grind-ten-thousand-hours".

Monolith is not revealing how much Gold will cost and says that prices will be communicated at a later date.

As you progress through Shadow of War, Mirian can be found throughout the open world.

There are two in-game currencies: Mirian and Gold.

In a blog post on the official Warner Bros. site, Monolith Productions said an internet connection is required to access Middle-Earth: Shadow of War's Market.

Some people began to defend Warner Bros., using the typical defense "it's only optional"... Would an always-online requirement make sense in light of the new microtransactions? Instead, Gold is created to provide players with a way to get their hands on certain items "immediately".

So if you just do the normal game, the game will be balanced for that. Gold merely allows you to get your hands on them immediately.
