Sentry guns is one of the deployable which will help shooing enemy.
Sentry guns have 2 variations, normal version and suppressed version. They both work the same way, but suppressed version makes them take less agro from the cops in which you wont break that fast. Deploying sentry gun will use some of your ammo (both primary and secondary), you can also retrieve the remaining ammo left in the sentry
Firing mode
Sentry gun have 2 shooting mode: normal mode(default) and AP mode(skills required)
Normal mode have rapid fire but it would not penetrade shields
AP mode shoots slower but have more damage and will penetrade enemy and shields
You can toggle the by interact with them
AP mode (outline in green color)
Normal mode (outline in blue color)
Left: normal sentry
Right: suppressed sentry
Repairing you sentry
Sentry gun are not invicible, they also have a health pool
After being attack constantly by the cops, your sentry will be damaged, if you do not repair it, they will be broken (blue electrical effect around it)
By simply collect back you sentry and deploy again, your sentry will be repaired
**once your sentry are broken, you can no longer repair it.
Non-upgraded sentry gun is very weak!

Since sentry gun will consume your ammo of both primary and secondary weapons, it is very important for us to have good ammo pick rate. Here are the suggestions:
Akimbo bernetti 9 pistols
High ammo capacity
High ammo pick up rate
High rate of fire
Low tiered damage akimbos
Since we are using the sentry as our main weapon, gun mod on these pistols does not affect much
Bernetti 9 pistols (why not?)
Same characteristics
Electrical brass knuckles
Stun enemy
Concussion grenade
Stun enemy
Improved combined tactical vest
Heaviest armor

• Sentry gun / Suppressed sentry gun (primary)
  
• Ammo bag (secondary)

Ammo is essential for this build, without ammo, your sentry gun will not be able to fight. However, keep stealing ammo on the floor from your teammate is not very good either. So sharing is the way we want.
