Pre-Game Prep

“	Start each game with a pile of permanent Road Spikes at the end of the track.	”
	^{~ In-game description}

Pre-Game Prep is an upgrade in the Powers Monkey Knowledge Tree, added on initial release. When starting a new game with this knowledge enabled, a pile of Road Spikes will be placed at all the exits of the track, popping 21 bloons each. It requires three points to be invested in the Powers Knowledge Tree, Longer Boosts, as well as 250 as a one-time purchase.

Explanation[]

Bp spikes — A fresh Bloody Puddles run with a pile of spikes at each of the six exits.

Pre-Game Prep sets a fresh pile of Road Spikes at every possible exit; maps with more than one exit contain more than one Road Spikes pile. However, an exit with multiple converging entries only counts for one Road Spike pile. Note that the bloons can collide with the Pre-Game Prep Road Spikes even if they originate from the entrance (notably on maps such as End of the Road, Adora's Temple, X Factor, and Flooded Valley).

This is to list a bunch of Pre-Game Prep statistics relevant to Pre-Game Prep strategization.

Beginner Maps[]

All Beginner Maps have only one Road Spikes pile near the exit, as the single lane consists of a single entry and a single exit (i.e. they are all single-entry-single-exit maps).

Strategy[]

Summary[]

Pre-Game Prep is a useful addition to helping make the early-game become easier, with the other being Mana Shield. This is especially valuable on Impoppable Mode, as Mana Shield is disabled in that game mode. The one major downside with Pre-Game Prep is the constant need to invest in the Powers Knowledge Tree in order to access this MK Point's perks. Also, Pre-Game Prep is sort of map-dependent, as maps with overlapping or closely adjacent entrances and exits may prevent Pre-Game Prep from being usable as an exit protector.

Tips[]

This knowledge can be very useful in tanking the leaking bloons in early rounds, especially in modes like Alternate Bloons Rounds, Half Cash and Impoppable Mode, especially for the last one since Mana Shield, another useful knowledge for surviving leaking bloons, is disabled for that mode.
Players can get a quicker understanding of how bloons travel on a new map by checking it with this knowledge on, since spikes will appear at where bloons will escape.
On some maps where the exit(s) are at the same place as the entrance(s) like Haunted, the bloons appearing on the first rounds may take away all the spikes before being able to appear on the track.
The Road Spikes from this knowledge wasn't affected by the Just One More knowledge until Version 19.0; prior to the update, the spike piles generated at the exit consisted of 20 spikes instead of 21.
Pre-Game Prep can be extremely useful in acquiring just enough money to purchase your hero without buying any other towers/losing any lives.

Trivia[]

There was a bug in Version 19.0 where the Pre-Game Prep's Just One More MK buff could stack indefinitely, particularly when reloading a game. It could work unless the player restarted the game. This was fixed in Version 19.1, and this bug was not at all mentioned on the official Version 19.1 patch notes.
