Unit

The Unit is an extension of the Cannon in Green The Planet 2, offering upgrades that improve the performance and functionality of the cannon. By upgrading the Unit, players can increase the number of barrels the cannon has and eventually unlock the auto-lock-on feature.
==Unit Level==
The cost of upgrading the Unit Level starts at 100 E and increases to 40m E. Each level of Unit adds an extra barrel to the turret, allowing it to fire 2-5 shots in succession instead of just one. It's important to note that the Energy spent on upgrading the Unit Level is refunded when transitioning to a new planet, so it should be considered an investment rather than a permanent expenditure.
Purchasing Unit Level 1 is recommended as one of the first upgrades on a new comet. The subsequent upgrades follow a peculiar curve, with level 3 providing minimal help for a relatively high cost and level 4 feeling expensive for just a moderate improvement. However, by reaching level 5, almost every weapon will fire a continuous stream, and charged weapons will charge much faster. Upgrading the Unit to level 5 can significantly enhance the gameplay experience, making it an enjoyable weapon upgrade to pursue after reaching around Planet 20.
==Auto Launcher==
The Auto Launcher is an upgrade available for the Unit, with each level costing 1 Billion Energy and increasing up to level 5. This upgrade enables the cannon to automatically fire in the direction of new comets. Each level of the Auto Launcher adds an extra "barrel" or unit's worth of firepower to the weapon.
The effectiveness of the Auto Launcher varies depending on the weapon being used. Slower-moving projectiles benefit less from Auto Targeting, while the Laser, even without Auto Targeting, can instantly hit and destroy its target, seamlessly moving on to the next target. The Laser is particularly powerful when combined with the Auto Launcher, making it highly recommended for players who rely heavily on this playstyle.
Charge type weapons can be fired by the Auto Launcher but require a full charge before they are launched. This means that the effectiveness of charge weapons is greatly enhanced when both the Unit and Auto Launcher are upgraded multiple times, resulting in significantly reduced charge times.
==Auto Targeting==
Auto Targeting is an upgrade for the Unit that becomes available for purchase at a cost of 5 Billion Energy. This upgrade takes into account the speed of the comets when shooting, enhancing accuracy. However, it is not effective for weapons that already have homing capabilities or instant-travel lasers. Unlocking and purchasing the Auto Targeting upgrade can be seen as a significant achievement in Green The Planet 2.
