2x speed and Modes, with restored prices and a pricier Sniper.
Monkeys vs. Zombies 2x + Modes adds BTD6-inspired game modes and a 2x speed button to Monkeys vs. Zombies. Pick Standard, Apopalypse, Double HP, Half Cash, or CHIMPS, then click the 2x button during a level to speed up the lawn.
Upgrade prices match the original Monkeys vs. Zombies for 360 tower upgrades and all nine Paragons. The Sniper's 15 upgrades cost 15% more than the original prices, rounded to five bananas, and a Sniper costs 175 to place. The Modes-only Storm Druid and Road Spikes upgrades keep their own prices.
Single player. Requires your installed Plants vs. Zombies: Game of the Year Edition and Bloons TD 6. Melty starts the mashup and points it to your games; the first launch prepares monkey art from your owned Bloons TD 6 copy.
Based on Monkeys vs. Zombies by HippieGod and Monkeys vs. Zombies: Modes by Stephen James, with the 2x speed add-on by isc iZo. Full library credits and license terms are included in the download.
