• the "Basic" feature set lets you change many otherwise hard-coded values of the game, and
  
• the "Advanced" feature set lets you change cop-spawning behaviour and tables without limits.
  

What does the "Basic" feature set do?

• at what time interval you gain passive bounty,
  
• the maximum combo-bounty multiplier for destroying cops quickly,
  
• how quickly and at what distances from cops the red "BUSTED" bar fills,
  
• how quickly the green "EVADE" bar fills once all cops have lost sight of you,
  
• when exactly (if at all) cops are destroyed if flipped over,
  
• when exactly (if at all) racer vehicles are reset if flipped over,
  
• when exactly (if at all) interactive music can transition to another track,
  
• whether cops in non-player pursuits can request ground supports,
  
• the internal cooldown for non-Strategy roadblock requests,
  
• the internal cooldown for Strategy requests,
  
• when exactly and at what distances (if at all) roadblock cops can join the pursuit,
  
• how HeavyStrategy 3 requests interact with non-Strategy roadblock requests,
  
• what vehicles spawn through HeavyStrategy 3 (the ramming SUVs),
  
• what vehicles spawn through HeavyStrategy 4 (the roadblock SUVs), and
  
• what vehicles spawn through LeaderStrategy 5 / 7 (Cross and his henchmen).
  

• which strings the game shows whenever cop vehicles are destroyed,
  
• which radio callsigns and chatter cop vehicles can trigger, and
  
• the selection (and order) of interactive music tracks in pursuits.
  

• helicopter mini-map icons are now always visible whenever a helicopter is active,
  
• helicopters no longer cast static shadows (like cars do) with incorrect placements,
  
• the game is no longer biased in how it chooses to make Strategy requests,
  
• Heat levels > 5 are no longer reset back to 5 when you enter free-roam or start an event,
  
• Heat levels > 5 are now shown correctly in menus (requires Binary for missing textures), and
  
• you can no longer get busted due to line-of-sight issues while the "EVADE" bar fills.
  

What does the "Advanced" feature set do?

• how many cops can (re)spawn without backup once a wave of reinforcements is exhausted,
  
• the global cop-spawn limit for how many cops in total may chase you at any given time,
  
• how quickly (if at all) cops flee a pursuit if they don't belong to the Heat level,
  
• what vehicles (any amount, with counts and chances) may spawn to chase and search for you,
  
• what vehicles (same liberties as above) may spawn in non-Strategy roadblocks,
  
• what vehicles (ditto) may spawn as pre-generated cops in scripted events,
  
• what vehicles (without counts) may spawn as free patrols outside pursuits,
  
• what vehicle spawns in place of the regular helicopter,
  
• when exactly (if at all) the helicopter can (de / re)spawn,
  
• how much earlier (if at all) the helicopter rejoins the pursuit when it loses you,
  
• the internal cooldown for the helicopter's ramming attempts through HeliStrategy 2,
  
• the player-speed threshold for HeavyStrategy 3 spawns to stop their ramming attempts,
  
• when exactly (if at all) LeaderStrategy Cross and / or his henchmen become aggressive,
  
• when exactly (if at all) the game can request a new LeaderStrategy once Cross is gone, and
  
• when exactly (if at all) the game can request a new Strategy while another is still active.
  

• non-Strategy roadblock and Heavy / LeaderStrategy requests are no longer blocked in races,
  
• early Strategy despawns or cancellations no longer stall the game from making new requests, and
  
• the engagement count shown above the pursuit board now (accurately) counts chasing cops only.
