Survival of the Fittest is a recurring weeklong event that consists of different stages. The first stage is called Construction Speedups. This guide contains some tips on how to do well.
In my state this stage is no longer available, it seems to be replaced by a Settlement Evolution stage, see link at the bottom of this article.
You get points for using Speedups on construction.
You can prepare for this event by making sure you have plenty of speedups and resources, so that you can score points by using those speedups, and use the resources to start new construction projects.
The most important tip is to be patient and use your construction speedups during the event.
If you want to use more speedups than you have in your bag, consider buying them at a discounted rate from the VIP store. The higher your VIP level, the more options you have to purchase those speedups. This will save you some Biocaps.
It is almost impossible to compete with big spenders for leaderboard on this stage. There will normally be plenty of spenders who purchase large amounts of speedups and saving up 2 weeks will not give you that much. Enough to win the point rewards, but not to rank high on leaderboard.
I hope these tips make it easy to win the Construction Speedups Stage of the Survival of the Fittest event. If you have questions or want to share more tips, please use the comment section below.
