October 26, 2009. The game has many new features, including but not limited to improved graphics, new towers and new modes. This game also has an expansion, with new maps and Specialties, which affect the cost of certain towers.

Gameplay

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 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.

Modes

Easy Difficulty

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

Medium Difficulty

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

Hard Difficulty

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

Sandbox Mode

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

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

Apopalypse

In Apopalypse mode, players have as much money and lives as in Medium, and things cost as much as in Medium (see above). Once the player click the 'Start Round' button, 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 players bonus money at the end of each round. If no road spikes/monkey glue were used completely, they will still exist.

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

Challenges

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:

Challenge 1: Pass Ocean Road on Medium with only using Dart Monkeys and Super Monkeys!
Challenge 2: Pass Sweet Tooth on Easy using only Dartling Guns and Spike Factories!
Challenge 3: Defeat a wave a 50 M.O.A.B.s with $50,000. (Pool Table)
Challenge 4: Pass Ant Hill on Hard without losing a single life!

Trivia

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, players receive less cash for popping bloons when in later rounds. They only get 50% of the normal cash for rounds 52-61 and 20% for rounds 62+.
The first challenge only lets players use Dart Monkeys and Super Monkeys, and it is very unlikely for players 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.
In the third challenge players can still place a Dart Monkey by using the hotkey D.
BTD4 is the first and only game to have Camo Bloons as a seperate Bloon, rather than a property.

Glitches

Patched

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

Not Yet Patched

Using hotkey abuse, players 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 players click on a tower and then right click on the road, and get rid of the menu thing that comes up, the player 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. This can complete the MOAB Madness challenge without placing towers.
Occasionally, the Missile Launcher will fire two missiles at once. This, however, is rare.
In later rounds, or on laggy computers, there will occasionally be a big black/white patch in the middle of the map. This also happens when too many road items are on the screen at one time.
With a tower or road item selected, if players RIGHT-click somewhere the player could normally place it, then LEFT-click anywhere on the map, players can place any tower or road item anywhere on the map.
