Gameplay discussion: Fully automatic varaints

Time to shift gears into automatic! These characters are mainly able to shoot for longer at a faster and more continuous rate. The benefits will generally come along with a cost attached to it, such as reduced damage or possibly losing traits that the character would otherwise possess.

You can use these characters to suppress your enemies and to retain fire on your enemies for longer without a break. These characters can autofire, meaning you can essentially increase their attack rate by constantly holding the fire button. 

Commando Pea: Has 30 maximum ammo (instead of the default 10). Your shots will deal 6-10 damage or 6-11 critical damage, which is dependant on the distance from you and your enemy. You lose the ability to deal splash damage and the damage of each of your shots is reduced, however you shoot at a much faster and automatic rate. You may be more likely to miss shots due to the increased fire rate, however missing your shots will be less significant as each individual shot deals less damage.

Bandit Cactus: Has 20 maximum ammo (instead of the default 10). Your shots will deal 9 damage or 10 critical damage, which is unaffected by distance. This allows you to retain your sniper capabilities. You are more likely to miss your shots, although you have a significantly improved rate of fire to make up for this, and missing your shots will be less significant as each individual shot deals less damage. Attack at closer ranges to land more of your shots, or at long ranges to take advantage of no damage dropoff and to essentially be a sniper.

Astronaut: Has 20 maximum ammo (instead of the default 5). Your shots will deal about 13-20 damage, which is dependant on the distance from you and your enemy. This is the only variant of Scientist who is unable to deal additional blast damage when extremely close to your enemies, so attacking at long ranges should work for you. You may miss shots more often at long range due to not being close to your enemies, however you actually have darn good accuracy even at further ranges and you have a significantly improved rate of fire, so this should not be an issue. Attack at closer ranges for maximum damage and to hit most of your shots, or at long ranges to prevent engaging with your enemies at close quarters.

Mechanic: Has 30 maximum ammo (instead of the default 10). Your shots will deal 6-8 damage, which is dependant on the distance from you and your enemy. You lose the ability to deal splash damage and this is the only Engineer variant that does not deal splash damage. The damage of each of your individual shots are reduced, however you shoot at a much faster and automatic rate. You may be more likely to miss your shots due to the increased fire rate, however missing your shots will be less significant as each individual shot deals less damage.

Breakfast Brainz: You have 2 different attacks, which each work in a similar way. Your punches become automatic, and continuously using it will increase your speed until you achieve an insanely fast rate of fire. Your beam is automatic as well and continuously using it will increase your speed until you achieve a significantly improved fire rate. If you use your weapons for too long, you will overheat. This is the only variant of Super Brainz who is able to overheat his punches. Your punches will deal a maximum of 13 damage per strike and your beam will deal 1-6 damage, which is dependant on the distance from you and your enemy. You will gain a temporary speed boost whenever you successfully vanquish an enemy.

Basic Notes

• You could use the Ammo upgrade on these characters, as they already have high amounts of maximum ammo and using this upgrade will improve their maximum ammo count further and allow you to keep firing for even longer. Breakfast Brainz gains the Overheat upgrade instead, which I suggest using as he can punch or use his beam for even longer before you overheat. 
• Using the Damage upgrade could be viable for these characters, as these characters deal less damage per shot, however using this upgrade will improve the damage slightly of every successful shot that you inflict, which could increase your overall damage per second. 
• The increased rate of fire could reduce your accuracy and cause you to miss a lot of shots. You could either use the Zoom upgrade to improve your accuracy while you are aiming, or try to attack your enemies at close ranges, and you should find yourself landing more shots.
• You may benefit from attacking a single enemy at a time, as all automatic variants listed above lose splash damage if they even would have had it at all, and your attacks can only deal damage to a single enemy at a time. Focus on gunning down an enemy, and then select another enemy to attack.
• You should hold the trigger when attacking to get the most out of these characters and maximise their damage per second. However, if you need to change direction to attack enemies and there are no enemies in the direction you are currently facing, you can let go to change direction and possibly reload while doing this. Give yourself a break while reloading as well!

These characters are interesting and are straightforward to use!
