Chests

Chests are the most consistent method way of obtaining various items, usually units or unit parts. Each chest offers different items and require different resources in order to open. If the player is able to open any chests with their resources (excluding gold), an icon will appear above the Officer's Club.

The general's chest is the most easily accessible chest that can drop natural 4-star and 5-star units at the cost of some gold or general's keys found in bundles. It is also has a much more expansive collection of natural 3-star units than the campaign chest, giving more diversity to the player.

The free chest can be opened without any cost with a cooldown in between and is the only chest that drops scrap, tech, and thorium along with natural 1-star and very rarely natural 2-star units.

Campaign chests are opened using campaign key fragments that are collected from the single-player campaign mode by either winning a campaign battle for the first time or through warzone missions. Campaign chests offer natural 1-star and 2-star units, though it can also very rarely drop a natural 3-star unit. Currently, it seems to be limited to Redpoint Viceroys, Greenbrake Basts, and Whitehawk Arbalests.

Raid chests are opened with raid key fragments that are awarded upon a successful raid battle. Raid chests drop unit parts for various natural 2-star, 3-star, and 4-star units.

VIP chests require a VIP level of 13 before it shows up in the officer's club at a much higher cost than a general's chest, but provides better odds at higher ranking units, guaranteeing a natural 4-star unit. The VIP chest also contains several event units such as the Claymore and variants of natural 4-star and 5-star units not found anywhere else, such as Bluesteel Kenels and Greenbrake Talarias.

Event unit chests drop rare event units from past events and require rare event unit keys typically only found during events. The units offered are usually from previous events and change from time to time. If the player has any keys saved for use at a later time, they should be wary on how long they plan to save the keys, else they risk losing out on the opportunity to get units that are rotated out and no warning will be given before the contents are changed. Note that the event units chest only offer variants of units that are not crafted using unit parts from their respective events. For example, the Viper can be crafted using Whitehawk parts from events, meaning the event unit chest can only drop Redpoint, Greenbrake, Bluesteel, and Goldfire Vipers.

Event part chests are similar to raid chests, dropping unit parts that belong to rare event units and require event part keys usually only found during events. Likewise, the parts that are offered are for units that were recently featured and can change at any time.

## Bugs

* When opening multiple chests of the same kind that drops units, such as campaign chests, the info panel on the right may not update correctly and displays the wrong unit abilities for the newly acquired unit. This error will carry on to the hangar where locked abilities will state that they are the (possibly wrong) abilities shown on the info panel. Once unlocked however, the ability will revert to what it is supposed to be. The error will also correct itself over time as well if the player never unlocks the erroneous abilities by promoting the unit.
	+ For example, a Probe may show that it has critical strike as its minor ability even though it is normally poison. Inspecting it in the hangar will continue to say that the minor ability is critical strike. Once the Probe promoted to 2 stars to unlock the minor ability, it will change back to poison.

## Trivia

* In the past, the raid chest functioned differently than it does today. It required 10 raid fragments to open and usually gave out various pieces of tech with a very low chance of a 4-star unit. This was changed to the current system.
* Many units seen on the banners of the various chests in the Officer's Club did not exist in the game at the time of the game's release because many of them are event units and events have not been added until much later. This includes the Sniper and Dryad as seen on the campaign chest banner along with the Strix and Antlion unit part on the raid chest banner after the change mentioned above was implemented.
	+ One possibility is that those units were intended to be included in the game when it launched, but had to be cut due to tweaks still being made to them and were then released later on as event units.
	+ Despite the raid chest banner showing the Strix and Antlion unit parts, it does not actually drop them and never will since both are event unit parts, which are dropped in the special event unit parts chest instead.
* Despite units being unable to be promoted to 7 stars in the past, the general's chest banner shows a 7-star Wendigo and the VIP chest banner shows a 7-star Gungnir before promotion to 7 stars was even possible.
* When events and the special event-related chests were added to the game, the event unit chest banner showed a Moray, which was unreleased at the time.
* Although it is not supposed to offer event units and has never done so in the past, the general's chest currently offers the possibility for a Totor or Pantalone.
* In the past, the campaign chest offered the same natural 3-star units as the general's chest.
