Impossible Creatures

Gameplay Changes And AdittionsEdit

  • Henchmen Lab Morale - Henchmen now do more damage to other henchmen when in sight of their lab. This enables players to repel "Henchmen Rushes" early in the game.
  • Artillery and direct range units had an increase in coal cost (approx 10% increase). This brings Artillery and Direct-Range units closer in line, power-wise, with their intended roles in the counter system and with melee creatures.
  • Henchmen now do slightly more damage vs. creatures, permitting a slightly better chance of survival against early rushes.
  • Pure swimming units are now significantly less coal. Previously there was no real reason for a creature to be a pure swimmer rather than amphibious- the only difference in cost was the minor cost of the added limbs. Now, players can specialize their forces for water-heavy maps and make large masses of creatures to rule the seas for a fraction of the cost of their land-walking counterparts, lending more tactical variety to water maps.
  • Updated Main Menu screen with a MOD selection feature. Download Insect Invasion and try out the new creatures, maps, abilities, and tactical elements. There is a new Campaign menu that makes it easy to play user created campaigns.

Multiplayer Map PackEdit

Relic Entertainment has released its first official Multiplayer Map Pack for Impossible Creatures.

Please Note: You will need to ensure that you have installed the Impossible Creatures Update v1.1 in order to play these maps online with other players. In addition, there is no Microsoft Product Support available for the use or installation of these maps.

Maps includedEdit

Double Twisted Bill, the lone user-made map in the pack, is credited to Bill Brooks (aka Zoltron_Bill), an incredibly active member of the Impossible Creatures community and a very talented map maker.


Bonus AnimalsEdit

50 animals just aren't enough when you're trying to create the unstoppable force and crush every foe. You may not know that in your installation of Impossible Creatures are ten more animals waiting to join the recombinant pool. Download the 1.5 MB file, install it, and you'll have 20% more chromosomes to deploy in your next battle.

The Steam edition of this game already has Bonus Animals unlocked.

Insect InvasionEdit

When you've played every map and every animal (and started to make a dent in the tens of thousands of possible combinations in your armies), you're ready for more. For absolutely no charge, you can download six free maps and 15 brand-new animals, which include several all-new combat abilities.


Please Note: You will need to install the Impossible Creatures Update v1.1 to activate this new mod. Also, if you previously installed the Insect Invasion Mod v1.0 you can run the small patch below to update your version of Insect Invasion rather than downloading and installing the full Insection Invasion Mod v1.4.


Note: Insect Invasion v1.4 can not be played in Multiplayer games against v1.0. Also, Insect Invasion v1.0 recorded games can not be viewed in v1.4
