Our biggest update yet brings a host of new content (including new creatures!) alongside official Steam Deck verification.

NEW CREATURES

Campaign, skirmish and multiplayer modes now have three new types of creature DNA available in the Splice-O-Tron.

  • The Beaver is a powerful amphibious engineer that can restrict enemy movement using its Build Dam ability and gains additional defense when starting a turn on water

  • The Scorpion can use its Clamping Strike to lock an opponent in place and its tail to place a deadly acid pool under enemy units

  • And the fearsome Red Panda gains health by attacking its opponents and can use its Ferocious Bellow to damage and drive back enemies

PASSIVE COMMANDER ABILITIES

Each of the 9 commanders now has their own unique passive ability. From earning cash by defeating enemy units to faster ability cooldowns, the new abilities open up new tactical and strategic possibilities for both campaign and skirmish modes.

Annabel Corman

  • Regenerative Byproducts - Headquarters tiles restore +100% increased health

Colonel Marcus Shaw

  • Terrain Boost - Hill/Forest/Mountain/City/Industry/Airport tiles provide increased defense

Major Nia West

  • Field Requisitions - Capturing a city heals all nearby friendly units for 30 health

Dr. Squance and Dr. Blevins

  • Vector Calculations - Friendly flying units move one tile further

Eric the Mutant

  • Atomic Resonance - Spliced ability cooldowns reduced by 1 turn

Gene Orson, CEO

  • Bounty Hunting - Gain Cash for every enemy defeated

Kaz Smith

  • Dr. Chuckles - Gain bonus Commander Power at the start of your turn

Sergeant Emi Takamoto

  • Priority Target - Enemy units already hit on a turn take +20% increased damage

Emperor Zarb

  • Superior Technology - Air units are discounted by -15%

NEW CAMPAIGN MODES

For players looking for a bigger challenge, we’ve added two new campaign modes.

  • Permadeath Mode - spliced creatures die permanently if they're killed in battle

  • Brutal Mode - The stakes are even higher in this mode where not only do splice creatures die permanently, but losing a mission ends the campaign

STEAM DECK VERIFIED

Earth vs Mars is now fully Steam Deck verified allowing you to experience the full Earth vs Mars campaign, multiplayer and versus modes on the go. We’ve made some UI, controller, and combat screen options to maximize performance on the Steam Deck.

NEW ACHIEVEMENTS

We’ve also added 6 new achievements based around the new creatures and campaign modifiers.

New Features

  • 3 New creatures – Beaver, Scorpion and the Red Panda

  • 9 Commander Passives

  • Added Permadeath campaign mode

  • Added Brutal Mode campaign mode

  • 6 New Achievements

  • Steam Deck Verified

Updates

  • Added a note about combat screen options to the tutorial

  • Localization updates for French, Italian, Germany and Spain

  • Minor UI layout and size tweaks for Steam Deck

Tuning

  • Reduced the number of units affected by Emperor Zarb’s mutate ability on normal difficulty. This will make that ability a little less punishing, especially on maps where there is a lot of combat

  • Increased the time it takes for the A.I. commander powers to fully charge. Reduces A.I. Commander ability spamming, particularly in missions with a lot of combat

Bug Fixes

  • Fixed a fog of war performance issue that occurred on some versions of the Steam Deck OS

  • Fixed an issue where custom maps may not have had the correct Commander options

Thanks for supporting Earth vs Mars. A lot of the changes we make to the game come from player feedback. So, please continue to report any issues to us at help.relic.com or drop by our Discord to chat with the team.
