In Blood Lab, you get a private lab filled with NPCs and fourteen weapons to try out. The blood moves like a fluid made of chunky cubes, spraying, dripping down walls and pooling on the floor. Spilling more unlocks new weapons and NPC models, and you can pick a layout, choose a blood colour and play with friends.
