PEAK's Roots update introduced a new biome and multiple new items. The Checkpoint Flag, although confusing initially, is one of the best items you can find. The most challenging part of using it is figuring out how it works.
How to use the Checkpoint Flag in PEAK
PEAK's Checkpoint Flag gives unconscious players a one-time use checkpoint before they die and turn into a ghost. Once you or a teammate gives up or dies, you'll respawn next to the flag, causing it to disappear. You can place a flag by holding down your interact or "plant" button on a valid spot anywhere on a level.

More often than not, if you or one of your teammates is about to fall victim to fall damage, spore poisoning, or other ailments that are tricky to cure over time, you'll die and turn into a ghost. Having someone use a Checkpoint Flag beforehand gives you a chance to try again without waiting for the rest of your team to make it to the level's peak.
Similarly, if you're playing by yourself, you can save yourself a lot of time by planting this down in a safe spot and attempting a risky climb. That way, if you fail and fall to your death, you'll have another shot at finding another path up.
The main downside of using the Checkpoint Flag is the setback you'll have if you fall from a high spot and have to trek back up. In some cases, the fog might've already caught up to you, causing you to die a second time. One of your friends might also unexpectedly use your flag, leading to a false sense of security if they don't get a chance to tell you.
You'll also have to watch out for unexpected enemies. Depending on the level, you may run into a random spider, scorpion, or zombie who wandered over. Double-check your surroundings as you place the flag, and watch your step as you respawn in case you get ambushed.
Although the Checkpoint Flag isn't directly related to any badges, it can help save your run, letting you collect more throughout the rest of your playthrough.
