GameplayEdit

  • Bloons TD 4's gameplay is extremely similar to the previous three games. As said above, Bloons Tower Defense 4 has many new features. These include:
  • Refined graphics. Bloons Tower Defense 4's graphics are heavily improved from Bloons Tower Defense 3.
  • New maps. The game has 9 free maps (3 beginner maps, 3 intermediate maps, 2 advanced maps and 1 expert map). There are also 8 Premium maps, purchasable with varying amount of NK Coins.
  • There are now 6 new towers: the Glue Gunner, Monkey Ace, Mortar Tower, Monkey Apprentice, Banana Farm, and Monkey Buccaneer.
  • New and improved upgrades for towers.
  • Ranking system, based on the number of bloons the player has popped.
  • Brand new Bloon types, also introducing the Camo Bloon.
  • Two new modes, Apopalypse Mode and Sandbox Mode.
Bloons will come non-stop until you run out of lives.
~ Official description of Apopalypse

In Apopalypse Mode, the gameplay is mostly the same, except for one key difference: there are no breaks between rounds, with spawned Bloons becoming tougher over time. The costs of tower and upgrades are equivalent to Medium Difficulty.

In Sandbox Mode, you have unlimited money and lives and you can choose which Bloons come and when.
~ Official Description

In Sandbox Mode, the player starts with $1,000,000 and 100,000 lives. The player can spawn any type of Bloons at any time. The prices are also in Medium.

ModesEdit

Easy DifficultyEdit

On Easy mode, things are cheaper than usual (85% of medium) and you start with 200 lives. There are 50 rounds to pass.

Medium DifficultyEdit

On Medium mode, things are regularly priced (see above) and you start with 150 lives. There are 60 rounds to pass.

Hard DifficultyEdit

On hard mode, things are more expensive (108% of medium) and you start with 100 lives. There are 75 rounds to pass.

Sandbox ModeEdit

In sandbox mode, you have 1,000,000 money and 100,000 lives. Things cost as much as in Medium mode (see above). In Sandbox mode, you can choose what Bloons to release and at what times. For example, you can click a button to release 20 Red Bloons, 5 Ceramic Bloons, or 1 MOAB. You can try releasing other bloons as well!

(Note: This mode is unlocked once rank 26 is achieved. Lives and Coins are NOT unlimited.)

ApopalypseEdit

In Apopalypse mode, you have as much money and lives as in Medium, and things cost as much as in Medium (see above). Once you click 'Start Round', bloons will never stop coming and continue to get stronger and stronger. Even though bloons never stop coming, rounds still exist, they are just started automatically, therefore Banana Farms still grant you a money bonus at the end of each round. If no road spikes/monkey glue were used completely, they'll still exist.

(Note: This mode is unlocked once rank 31 is achieved.)

ChallengesEdit

Bloons Tower Defense 4 introduced a new gameplay called Challenges. These challenges include limited towers and a certain track. Every track allows Road items. Only 4 has been made:

Premium UpgradesEdit

Bloons Tower Defense 4 features Premium Upgrades for various new tracks and new abilities for towers.

TriviaEdit

  • The actual last round is round 250 because there are no rounds programmed after.
  • Round 250 has 999 B.F.Bs, and it is almost impossible to reach that level without cheats.
    • Similarly to BTD5, bloons gain speed at higher rounds.
  • In BTD4 and all subsequent Bloons TD games, you receive less cash for popping bloons when in later rounds. You get 50% of the normal cash for rounds 52-61 and 20% for rounds 62+.
  • The first challenge only lets you use Dart Monkeys and Super Monkeys, and it is very unlikely for you to have a Super Monkey with Plasma vision before Round 28. The Premium Upgrade, Exploding Darts allows you to pop Lead Bloons without using Pineapples.

GlitchesEdit

PatchedEdit

  • The hot keys allow use of the towers, even if not unlocked.
  • You can no longer activate Premium Upgrades without even paying NK Coins (This was done by clicking the edge of an upgrade button).

Not Yet PatchedEdit

  • Using hotkey abuse, you can place anything anywhere.
  • When the Boomerang thrower throws his boomerang, his boomerang sometimes won't return to the tower but will vanish at about two thirds of the way around.
  • If you click on a tower and then right click on the road, and get rid of the menu thing that comes up, you can place the tower on the road.
  • When there are many bloons on the screen, and when the Bomb Tower shoots its bomb/missile/MOAB Mauler, the player doesn't see it explode even if it hits a bloon. Same with the Mortar Tower and the Fireball.
  • On old computers, in the early levels, the game may freeze when you start a round, and then the round will be finished without a single bloon ever appearing on screen.
  • Occasionally, the Missile Launcher will fire two missiles at once. This, however, is rare.
