An ecosystem combines living organisms and the environment, which exist in close connection with each other. A change in any element affects the entire ecosystem, but due to its stability, equilibrium is quickly restored. Sometimes, a random event leads to the butterfly effect, an unpredictable cascade of changes that can completely transform the

Butterfly Effect is an add-on expansion to the game Evolution: New World. The new animal traits allow you to fine-tune the game ecosystem, create new survival strategies, and maybe even win the Alien World scenario.

With Butterfly Effect, you can increase the number of players up to 6, or play solo against merciless Dominator or Devastator.

This is an expansion, and cannot be played without the core game, Evolution: New World.

With Butterfly Effect, you can increase the number of players up to 6 by adding the expansion components to the base set of Evolution: New World. If you’re playing with two or three people, simply remove half of the cards for convenience
— the game includes 2 copies of each trait and Area card, except for the Anglerfish card (6 copies).

The larger Dominator and Devastator Alien Boards are used in the 1 player Alien World Solo scenario.

Aliens in Evolution: New World aren’t the aliens from outer space. They are just new and unfamiliar species, based on the creatures that either inhabited Earth a long time ago, inhabit it now, or very well could inhabit it in the future.

The Alien World Solo scenario is designed for a single player, although a friend's sound advice can be useful when confronting the Aliens – the scenario can be played cooperatively too. In this case, all players collectively control one population of animals, so neither the gameplay nor the number of cards in play change.

In the Solo mode, you compete with an Alien that has a big advantage from the very beginning and is very strong. However, it lacks imagination and always operate according to a clear algorithm, predictable and mindlessly. Where there is predictability, there is a chance to outsmart and win.

Solo Gameplay

From the players’ perspective, the Solo mode plays mostly like the one-vs-many game, so it really teaches you to play the game. The Solo mode is faster than the normal game and lasts for just four Epochs. The setup for a player doesn’t change, but the Alien starts with three animals, each with four traits – that’s definitely something you shouldn’t underestimate. The Epochs deck consists of four cards, but otherwise it is considered a two-player game.

• During the Development phase, you create animals and add traits to them according to the normal rules. The Alien skips this phase.

• Areas Phase doesn’t change – you draw a new Area card, so three Areas are available each turn.

• In the Feeding phase, the Alien always takes the first turn and follows a preset algorithm. Each turn, one of its hungry animals takes a basic action, until there are actions they can take. They take food from the leftmost Areas and attack your leftmost animal – so, you always know what it’s up to.

Each Alien have a set of traits that all their animals have, and special abilities that ensure a unique gameplay and experience.Chaos theory studies the behavior of complex dynamic systems, which include ecosystems. The term butterfly effect is used when a small change in initial conditions leads to large, sometimes catastrophic consequences.

In this scenario, a random event occurs in every Epoch. However, players have the opportunity to profit from the event or at least minimize their losses.
