Bionisation 4

Players exploring the world can catch several kinds of bacteria and viruses by eating raw meat or by breathing in particles from an infected mob during an attack. Mobs carry a blood level that reflects their immunity and strength, and it drops through bleeding. A player who dies with a weak immunity keeps the infection effects, and these can grow stronger over time. Some infections show particle effects, and a few bacteria and viruses are defined with specific particles.

The effects fall into three groups, and common viruses and bacteria are the simplest of them. Wild viruses appear with a random genome, so the same name can carry different effects in different worlds. The Bio Analyzer shows which effects a player has, unless they are hidden. Recovering from common effects needs only simple things such as drinking water or wearing armor against sunstroke, while more complicated effects call for a cure made from genes the player has identified. Players collect herbs from drops and use them in items and machines. Bio armor gives protection against some bacteria types and airborne viruses, and keeping pets and animals safe from danger is part of the design.
