Teotihuacan: Late Preclassic Period is a modular expansion which introduces several new options to enrich and expand the game experience. Asymmetrical player powers give each player a unique benefit. A prestigious fourth temple allows unlocking of permanent powerful abilities, while being much more difficult to advance on. Variable effects impact each season and eclipse. New engineering techniques and renewed plans for beautifying the central Pyramid of the Sun offer fresh challenges and possibilities. All modules are compatible with one another and can be enjoyed together or individually.
