Exploding Bridge PvP Challenge

With a few squad members missing, we decided to pause our 5 Defenders Challenge and dive into a PvP match instead. The group discussed and agreed on a map called “Exploding Bridge.” The twist? The bridge connecting Red Team and Yellow Team explodes every 7–10 minutes, which means...

Learning to Communicate Effectively 🗣️

Today we struggled. Our main power source was blown up multiple times and we didn't know how to organize ourselves to fix it.

After a few lengthy conversations and some long pauses, this is what we've come to agree on:
- If someone is talking, let them finish before you start t...

Stretching our Brains 🧠

Today we took on a very hard plastanium production challenge. In this challenge, you need to produce 250 plastanium, but there's a catch! Once you reach 200 plastanium in your core, your core begins to burn plastanium. The only way to reach 250 is to produce 2 full lines of plast...

Taking on Chasm! ⛰️

Today we took on Chasm, and incredibly well designed attack map by one of the kids at *****!

We Finished Groundwork! 🚀

On our first attempt last week, we failed on wave 5. After failing the challenge we reflected and came to the decision that we need better planning and division of labor. This lead to us splitting into two groups:

Debugging Our Way Through “Levels”

Teamwork and Resilience

Hey everyone,

Over the past two weeks, we've been working through a tough challenge with the Geysers map. It hasn’t been an easy ride—at times, we’ve hit some real roadblocks. We started strong, but as things got more complicated, our defenses broke down, and we all know how dif...

Chasm Round 2! 🏔️

Based on our reflection from last week, we made three big changes going into the challenge today.
