Base Race is a challenge in two stages, and you can choose whether to participate in one or the other (or both!) of these stages.
The first is to gather up the list of items and assemble them in the chest.
The second stage is to use those items to create a build to the set theme.
At the beginning of the map you'll be given several choices, which will change the game and make the experience much more unique for every player!
About the Map
Base Race is a monthly challenge, with new maps being released on the last day of every month.
This particular map was created for July 2017 with the theme: "Science". It can be played solo or multiplayer.
I highly recommend watching the announcement video to get all the information you will need: Announcement Video
You must gather a chest full of specific ingredients, without creating a new bed or harvesting materials from the spawn base. You will start in the Choice Box, where you will have four options that will change your Race:
1. Whether you're playing both stages (or just the race stage) OR just the Base stage.
2. A choice between two items to collect/build with OR a different two items.
3. A positive ability/effect or addition.
4. An extra challenge for your race.
Using the items you collected, you create a build to the month's theme.
Check out the rules video to see how the different coloured numbered items can be used: Rules Video
If you are playing the current month's Base Race then you can submit your build on the forum for the random draw, to see if it will be used as the spawn base in the month after next. You can also use the forum to be added to the player list for that month and post up videos.
If you are a patron to The MobCave you unlock a special extra reward. A mostly cosmetic addition, which is different each month, and is designed to add to the fun of the map without giving patrons a benefit over other players.
