Bloons Tower Defense 4 (Adobe Flash)

Bloons TD 4 is the fourth tower defense TD game in which you pop Balloons 24/7.

Unused Graphics#

btd5_btn is an unused button that gets loaded offscreen. It was used in earlier versions and was replaced by the "Play BTD5" button on the main menu.

Tower STILL exists in BTD4. It is an unused sprite that may have been used for testing towers. It also exists in Bloons Tower Defense.

The Spike-o-Pult, a tower from the previous game, exists in the game's files. The Multi Shot upgrade from Bloons TD 3 exists too..

..with quite an odd oversight; the flag the Banana Republic upgrade of the Banana Farm has appears as one of the catapults mid-frame.

Sprite 1173 contains a hide button. However, what it does is the opposite. It is used to hide objects on-screen. It was hidden off-screen. [1|The hide button in action]]

Unused Tower Rollovers#

Every tower has a mouse rollover graphic but, for whatever reason, aren't used.

Track Editor#

The Bloons Tower Defense 4 Track Editor was a separate application for Bloons TD 4, but it seems that wasn't always the case. There are very early unfinished graphics for the track editor internally.

An early menu, consisting of only a view of the player's tracks, popular tracks by other players, and track creation button. The final Track Editor has no equivalent to the "Exit Track Editor" button. This is because it is standalone and not part of the main BTD4.

An early editor, with placeholder pieces and a blank map. The editor has 7 map pieces(unlike the final editor's 16), the internal green start and red end points of maps in the final game (which are used as placeholders here), an early eraser (the white box below the start/end points), no backgrounds meaning a blank white space, and no graphics.

Offscreen, dark red buttons exist, which are probably the save and test buttons as empty functions for them exist internally.

Hidden Graphics#

The green and red graphics are used in the final game, but they are hidden outside and under the maps, so they cannot be seen during gameplay. The red graphic is used for map exits, and the green graphic is used for map entrances, and the white graphic is an early eraser button, as mentioned earlier.

Unused Text#

Clear Cookie

There is a button hidden outside of the loading screen to clear cookies.

The Dartling Gun operates under your orders!
   The gun spews a fast stream of darts to
    wherever your mouse is during a round,
   allowing you to direct firepower exactly
      where you need it when you need it.

While not unused, this text cannot be seen because the Spike Factory text immediately overrides this text when both the Dartling Gun and Spike Factory unlock.

Call in a storm of Super Monkeys - expensive, but it will wipe the screen clean of all bloons. Has a 60 second cooldown, not counting between round time.

The Monkey Storm in this game is watered-down to an ability button, unlike in the previous game where it is classified as a tower with its own tower button. Despite this, an updated version of its tower description from the previous game exists, having a new sentence.

Hurls a huge spiked ball that can pop many bloons at once in a straight line.

Oh? A completely new description for the Spike-o-Pult tower from the previous game! This suggests that the tower was not immediately turned into an upgrade for the Dart Monkey, even if it did not last long..

7k7k suck dog penises

In the game's setting script, one of the website domains is... pretty interesting, to say the least. 7k7k is the name of a Chinese browser game website.

Unused Code#

 
case "spikeopult1":
return GetPrice(COST_SPIKEOPULT_RANGE_UPGRADE);
case "spikeopult2":
return GetPrice(COST_SPIKEOPULT_JUGGERNAUT_UPGRADE);
case "spikeopult3":
return GetPrice(COST_SPIKEOPULT_RATE_UPGRADE);
case "spikeopult4":
return GetPrice(COST_SPIKEOPULT_MULTISHOT_UPGRADE);

Upgrades from the previous game's Spike-o-Pult tower. Since they only have upgrade cost data, it is clear that they are just leftovers, though the Spike-o-Pult tower is set to unlock the Multishot upgrade at rank 19, which was carried over to the Dart Monkey once it was shifted.
