Another break from the usual Arknights' tower defense gameplay, our good ol' friend Cannot Goodenough invites us to attend his specially prepared "Terra Investment Master Class" so that we can earn more Originium Ingots and excel in Integrated Strategies, as promised. The gameplay is similar to Totally Accurate Battle Simulator where an army of two enemies are pitted against each other to see who is the best among them, but the player also needs to actually bet on which side is going to win, hence why it is called an "investment" (even though it is more appropriate to be considered gambling).

To start with, the player just need to click on the picture on the bottom-right of the IM menu to enter the battle. The player will then be taken to an operation where unique to this one, enemies will attack and can block each other, and are divided into two sides: Red (the column of Incursion Points) and Blue (the column of Protection Objectives), down to their HP meter.

The battle is divided into several rounds with differing enemy lineup each. Before the round starts, the player will be given the option to place their bet invest on either side, using part of their starting balance of Originium Ingots:

Putting down some loose change 10%
Wagering a decent chunk 30%
Throwing caution to the wind 60%

Once the bet investment is made, the round starts and the enemies duke it out with each other. The round ends when either side lost all of its members; if the side the player bets on invested in wins, they will receive more Ingots than the wagered invested amount, otherwise they will lose twice the wagered invested Ingots. In case of a tie, both sides are considered to have won the round. Should the player's Ingots drops to 0 from consecutive defeats, they will fail the battle and had to start over.

The amount of Ingots received upon winning a round increases with consecutive victories, which is always rounded up to the closest decimal number (e.g. 99.09 is rounded to 100).
