I realize now how badly I described that.
Adds news enemies that will be dispersed over the world. This increases the RAM requirements. With 1 variation for each biter, worm, and nest and 5 tiers expect upto a 2GB RAM increase. With 20 variations and 10 tiers set expect up to 9GB RAM increase. Variations add randominess to each tier of biter, worms, or nests. Tiers are the power level of the biters.
The above is going to replace the current description on the settings.
Please let me know if that answers your question.
Also this is the wrong spot of the rampant arsenal talk, but the player has access to a mortar are you talking about a larger fixed building?
Cruise Missile, how is this different than the two rocket turrets already?
Rail gun, so like a large cannon cannon?
Also what do consider long?
