Hi everyone,
In the spirit of keeping you up to date with development, we've got a short update on our plans for the next ZEPHON DLC.
Previously we talked about repeating another standard Q4 content pack. As development has progressed, we've decided to narrow the scope and focus the DLC entirely on new units.
Q4 DLC
The next DLC is currently planned for Q4 2026 and will include:
Tier 7 Human antimatter sniper infantry with a personal gauss drone
Tier 8 Human large heavy railgun walker
Tier 7 Voice echolocation infantry firing crippling needles
Tier 8 Voice large legged fleshflower firing damaging and healing spore sacks
Tier 7 Cyber coil-based debuff infantry
Tier 8 Cyber large long range hovering artillery
Tier 6 Chieftess monster truck siege rig with battleship artillery barrels
We may also add a couple things for free to the base game with the DLC's release. We'll share more details as we get closer to release.
Until later,
Survive.
