Final Thoughts

Finding every collectible in There Is Only War requires exploring side routes and checking unusual walls, platforms, and ruined structures. Munitions Mayhem has the highest number of Secrets, so take your time around the missile silo, loading depot, and final arena.

Remember that collecting all the Secrets does not automatically count as collecting the Purity Seal. Check both counters before finishing each level. If you miss anything, you can replay completed levels through Level Select rather than restarting the entire campaign.
