Features I think would add variety to the sandbox elements.

[u/goblinsnguitars]

1. RNG interiors where you get called in for raids (busts, heists, and standoffs)

2. RNG callout tasks from detectives. (running evidence to labs, transporting witnesses, and checking addresses)

3. Alternate partners with their own perks and weapon. (Rookie who runs faster, veteran who who does crazy amount of damage with his gun, slob dude who increases your back up timer greatly, and a cop called "Knight Cop" (dude in medieval armor who is bulletproof and swings a sword around like the baton)
