Activision and Infinity Ward have been keeping their lips shut when it comes to Call of Duty: Modern Warfare battle royale info but a recent leak hinted at battle royale mechanics for obtaining gear that were present in Radical Heights.
Call of Duty: Modern Warfare's battle royale mode is all but official. It's literally only the official announcement that is lacking since people speculated about the mode for months, several data mines pointed to it and now another leaked bit of code showed the names of the areas that will be found around the battle royale's map.
- Gas Station
- Gun store
- Police Station
- Train Yard
- TV Station
Bank is particularly interesting here because of the few battle royale exclusive items that were also leaked. The items are Medical, Armour, Alcohol and Plunder. The last one appears to be an in-game currency but it's not entirely clear what it will be used for. Considering Call of Duty Points are already confirmed to be the currency used for cosmetic and possibly other, game-altering purchases, it doesn't make much sense to introduce another one for the same purpose.
This is where things get really theoretical and you should take them with a grain of salt. Radical Heights, the ill-fated battle royale by Boss Key Productions, had a unique system of obtaining powerful gear for a battle royale. Some items could be found around the world as per usual, but some powerful weapons, armour and grenades could be found in vending machines.
Players would get access to those pieces of gear by spending money they earned from breaking cash registers, killing enemies and other means. They could also use an ATM to store that money in order to purchase cosmetics in the game's shop later on. By now it should be obvious what we're implying.
In theory, it's possible that players will be able to obtain Plunder by playing Call of Duty: Modern Warfare battle royale and decide to spend it for higher chances of winning a match or save it in the Bank for possible cosmetic purchases later on. Keep in mind this is all just speculation based on data mined information, that also didn't seem too far fetched at the time of writing.
