Classic Hex Grid Tactics
Immunity Wars is a classic hex grid tactical experience. You'll use each battlefield's terrain to your advantage, play against your enemy's weaknesses, and take all the time you need to plan your every move. With each passing level, your foes will truly put your tactical skills to the test, with likely multiple plays needed to defeat the toughest of enemies.Combine the Strengths of Your Immune System
Throughout the game, you'll unlock access to more of your immune system's defenders. Its up to you to understand each unit's strengths and determine how to best put them into action, working them in tandem to achieve victory on every level. By nature, the immune system's components must work together to survive, or die trying.Battle Against Real Diseases
This game uses real research to determine how your immunity units and the enemy pathogen units will act. This means you must use the real processes that your immune system goes through to stamp out a variety of invaders, with every new enemy encounter throwing a wrench in the carefully balanced system.
