Into the Future is the second saga in the game and is unlocked after you complete Chapter 1 of Empire of Cats. This mode contains 3 additional chapters, with 48 levels in each once again. This mode also introduces Timed Score Rewards, in which you gain bonus gifts the faster you can complete a stage.
The main gimmick of this saga is the debut of Alien Enemies; they are much stronger than the EoC enemies, don't give much cash, and have a 700% Strength Magnification by default, of which can only be weakened by the Anti-Alien Crystals you can obtain as Treasures.
Lastly, the price of your units is that of Stories of Legend and EoC Chapter 2. Example: Macho Cat is $75.
Chapter 1-Time Enough for Cats
Boss of this Chapter is Cli-One, with a wave of Alien peons.
Players unlock additional Cat Combos upon completion.
Chapter 2-Alien Intrigue: A Maiden's Revenge
Old aliens not introduced in this chapter have a strength magnification of 250%.
Players unlock Valkyrie Cat's True Form upon completion, the Holy Valkyrie Cat. Gains a ~50% attack boost, and a 35% chance to freeze all enemies (except Metal) for 2.917 seconds.
Chapter 3-The Ancients Arise: Take Back Earth!
Old aliens not introduced in this chapter have a strength magnification of 500%.
Boss of this Chapter is the Raging Bahamut Cat, with an even stronger wave of Alien peons.
Players unlock Bahamut Cat's True Form upon completion, the Awakened Bahamut Cat. Becomes more of a kamikaze unit, with extraordinarily high DPS, insane movement speed, much less Time Between Attacks, and a very short attack animation. However, it's range is now mediocre, probably as a way to balance it.
