Deflation (BATTD)

"More starting cash but no cash can be gained from any other sources."

- BATTD description

"TIP: DEFLATION Invest wisely! In this game you won't get any income from popping bloons, completing rounds, or other sources like Bro Fist or BMO.

Spend your starting cash to build a perfect defense. Remember you can sell characters to reclaim some cash if you need to."

- Cuber's description to Deflation rule in the Martian Games Deflation a rule in Martian Games. It returns in BATTD from other BTD games with the same functionality. The player starts with a flat $50,000 and cannot gain anymore of them through any means (i.e. cash from bloon pops and round completion, bonus income per pop, income generation), not even from the Magic Coin Purse, but selling will still refund cash.

Trivia

 * If BMO or Holiday BMO is placed while Deflation is active, they will be disabled just as they would when reaching the $10,000 income cap in non-Deflation Martian Games.
 * Income only related upgrades such as Tuxedo Jake's Busker and Dr Monkey's Alchemy can still be bought. However, they will have no effect.
 * Items that give both cash and lives (e.g. Bro Fist, Thought Cannon Wand, COBRA) will drop them as usual, but the player may only receive lives and out-of-game items (if any) from them.
