Gameplay Changes/Additions

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.

Technical Changes

Updated Sound Engine, which supports a new Patch & Sample Editor that is available with Tools Download on the Relic Developer Network. 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.
