All games begin at this, the most basic of all the Research Levels. Players have access, wether directly or indirectly, to most buildings at this point. Once a Creature Chamber is built, a player may create Level I creatures straight away. These creatures are the weakest in the game and do not have many abilities but can be useful to defend with while setting up a base, or even for an early rush against the opponent.
Players will have access to the Water Chamber and water-bound creatures upon reaching this level, as well as the Genetic Amplifier. Ranged creatures and abilities such as Leap Attack appear in this Level, owing for more diverse combat between opponents' armies.
Unlocking this Research Level grants access to the Air Chamber and flying creatures, presenting even more options for battle. The Poison-based abilities also appear here. This is often when battles can start to get really intense.
Research Level 4 unlocks a few new items at the Research Clinic. Creatures of this Level are well-rounded in offense and defense or have especially high attacking power. Defile Land and Loner are also available at this point.
Level 5 creatures are the most powerful, and most expensive, in the game. Their attack power, health and defense are often very high, or it may be that their damage output is extreme. Creatures of lower Research Levels generally have little hope of standing up to them, assuming numbers are equal on both sides. Combat between Level 5 creatures is vicious and both teams can end up with serious casualties.
