Bloons Tower Defense 6/Balance changes

This is a list of balance changes throughout the game history.

Version 11.0
See also this Reddit link.

New Features

 * Full 2-4 player Co-op mode:
 * Co-op mode unlocked at level 20 for all maps.
 * 13 New Co-op achievements.
 * Special Co-op badges.
 * Quick and easy matching making lobbies to get you straight into the action!
 * New option to play immediately with friends. Share your lobby codes with your friends to invite them into the action!
 * Two new maps:
 * Cargo - A brand new track with a brand new challenge, it’s freighteningly good.
 * Park Path - A trip down memory lane for some of you from another game with monkeys that we know and love.
 * New Hero Skin: DJ Benjammin’.
 * New Fireworks Theme & Collection Event (July 4th theme)

Key Features

 * Races have had a small rework which now adds a 0.2s delay between sending rounds. Multiple button presses will still queue up and release the rounds after this delay.
 * Freeplay difficulty scaling and bloon groupings have had a massive rework to be considerably more difficult. Only Rounds 101+ are affected.
 * 2 new options added to the challenge editor to spawn all Bloons & MOAB Children as ‘All Camo’ and/or ‘All Regrow’
 * Towers should no longer ‘move slightly’ when you raise your finger, which would cause them to show valid placement while in a spot they couldn’t actually be placed
 * Daily Chest rewards have been reworked to be overall a little more rewarding and varied
 * Positioning towers has been improved. Towers will stay closer to the cursor/finger location to provide a more precise and smooth experience.
 * General performance improvements.

Co-Op Specific Balance Changes

 * The BTD6 app will synchronize Co-Op Mode gaming progress every so often, particularly for 4-Player Mode. In some cases, the game may intentionally paused and/or refreshed every so often, in order to synchronize the Co-Op server.
 * Multiple Heroes may be placed, but XP Points are divided among each player's Hero.
 * Each player can have their own tier 5s so no one gets locked out from their build choice by another player
 * Eco is split fairly so progression is moderated.
 * Private matches allow any platform to play with any other platform on the same version.
 * Quick game matchmaker does try to create games between similar platform performance metrics first.
 * Game input system was substantially revised. Mortar set target and Heli set patrol points now start with defaults and can be set from there. Tower portraits now need to be double tapped to get upgrade details (can’t single tap if already selected).
 * Track relative positions were shifted slightly on some maps for co-op play: Pat’s Pond, Underground & End of the Road.
 * Double Cash is not enabled in co-op currently - this is part technical and part fairness/fun. It is currently labelled single player only and we will be watching this with the community closely.
 * Co-Op Races and Co-Op Challenges are planned but these are not in this first release. They will plan to add those two later on.

Bug Fixes and General Changes

 * Added ‘Half-touch’ functionality. When the UI is open for a selected tower, tap and hold on the base of the tower to hide the UI and fully display any targets and or range it has.
