Rapid Gun

Description
The Rapid Gun is the first weapon upgrade available in the game once the player reaches level 2. In the game files it is named "Cannon1".

Compared to other weapons and the Default Cannon, this could be the closest to an upgrade of the latter due both sharing similar mechanics than with the rest.

This time, the projectile fired from the Rapid Gun is a white ball with a red ring around it.

Upgrades
It has a much faster fire rate than the Default Cannon, able to fire 4 shots per second and in turn deal with multiple targets with ease specially if they are not too scattered accross the screen. Its bigger clipsize also lends itself far easier to this, becoming a more reliable choice.

With this weapon comes the introduction of the Recoil and Recover mechanics. If the player were to shoot all 30 bullets non-stop, accuracy degrades faster than it can recover. The reticle increases in size to reflect on this as well. Compared to the Default Cannon, with this weapon the upgrades related to Recoil and Recover do have an effect.

Once Rapid Gun is acquired, Tier 2 of the Cannon weapons becomes available for the next time the player opens the Upgrade Screen.

Strategy
While the Rapid Gun is a straight upgrade from the Default Cannon, it's perhaps better to choose some of the other Tier 1 weapons, or the next Cannon upgrade instead. It is capable of dealing with small enemies well but still requires more shots to handle bigger ones and is incapable of handling Boss battles.

There are times in which it's best to shoot twice at a single enemy in case it drops a bonus, as well as go for rows of enemies first than for the more scattered ones, for any possible bonuses.

In the event the player prefers to keep the Rapid Gun, the best upgrades for it are Fire Rate and Damage. Reload Time is fast enough to not worry about incoming enemies, and the Recoil value takes a longer while to become a problem that such can be ignored while choosing other upgrades instead.
