50M milestone — blue only

Once Squad 1 passes 50M, use only 5 blue-faction heroes to keep growing. This is the shift from "use the strongest heroes" to "use a synergized squad". At this power level, a faction buff of about 10% is worth more than the gap between individual heroes. ■ Why blue Based on the experience shared in "Squads 1, 2, and 3", blue beats red and blue is the faction to develop first. An all-blue Squad 1 also lines up with the Shooter research line (see "Military Theory") and the Dawn Tower hero building. ■ Prepare before you hit the mark Do not wait until you pass 50M to start collecting blue heroes. While Squad 1 is approaching the mark: 1. Check whether you already have 5 orange blue-faction heroes. 2. Put orange hero shards into blue heroes that still lack stars. 3. Prepare gear: when you switch squads, you may need to move orange gear onto the new blue heroes. ■ During the switch • Squad 1 power may drop slightly right after swapping heroes if the new blue heroes are still weaker than the old ones. This is normal. Keep raising them, because a synergized squad is stronger in the long run. • Move heroes of the other faction (usually red) to Squad 2 so your earlier investment is not wasted. ■ After 50M From here, all hero resources (experience, shards, gear, energy cores) should go to the 5 blue heroes in Squad 1 first, then Squad 2. See "Biggest power spike moments" for where to invest first.
