Gems

Gems are available from picking up question-mark boxes. They provide upgrades for your ship stations:

Types Of Gems[ | ]

Different gem upgrades are as follows:

Component	Power Gem	Beam Gem	Metal Gem
Turret	Gives the Turret one more barrel, which increases fire rate	The Turret turns into a beam gun, that is slow to charge up but yields a medium amount of damage	The Turret turns into a morning star like weapon that can be thrown out. It's difficult to handle, has somewhat limited range, but deals great damage
Shield	Makes the Shield larger	The Shield becomes able to reflect enemy projectiles	The Shield becomes solid and spiked and capable of ramming enemies. It does not turn off when moved, however it is much slower than other shields
Engine	The engine receives 2 speed boosts that charge up automatically.	Turns the Engine into a beam cannon. While using the Engine it charges it's beam. Once charged the player can shoot the beam from the Engine's Nozzle by releasing the throttle. Cannon does medium damage.	The Engine shoots caltrop like objects from its nozzle which damage enemies slightly
Yamato	Fires multiple homing missiles	Fires a powerful straight beam laser	When deployed a big saw blade circles the entire perimeter of the ship dealing heavy damage, albeit with somewhat limited range.

After upgrading a station, it can hold two gems. This makes combinations possible.
