Squad members
Some of them members (red and yellow) cause more damage, while others are meant for support and healing. However, they all can cause damage and attack monsters. Create a strategy and match tiles properly.
Each squad member has three different special attacks. Consider their effects and use them at the correct moment. The special attacks become available by matching tiles corresponding to the color of your character. Each time this is done, they will get extra energy which progresses towards unlocking their special attacks. The first special attack usually does damage and nothing else. You can opt to wait to completely fill the meter. Some special attacks are better than others.
It is usually not worth charging a hunters' special skill to level three. However a few hunters have high-level skills that are worth the time and effort needed to charge them. It is usually better to use lower-level skills often instead of waiting for higher-level skills to charge.
Hank is the default "Yellow hunter". His special skills are charged up by matching yellow tokens with a shield emblem. Hank's most useful skill is "orbital barrage," which is readied by matching enough yellow tokens to reach skill level three. Orbital barrage allows you to fire a laser that destroys a 9x9 grid of tokens.
Val's healing ability is important. Her level two skill is a Med Gun, which restores one hunter's health by 40% and removes status ailments such as poison.
Use Markov's level two skill, Lightning Gun, to delay enemy attacks. It damages all visible enemies. It also delays enemies' attacks by one turn.
