It's a superb addition to a pretty fun game that fixes or improves just about everything that sucks about the base game. It adds bug fixes, characters with stories and events, and interesting mechanics that bring the game to life. Most importantly if you have an idea, it could potentially be worked into the mod. The discord is welcoming and helpful. It's really a necessity if you want to try Lab Rats 2. I was skeptical LR2 could get better with mods after I first found it a year ago, but these guys really blew it out of the water. Once you've played with this you no longer see it as a mod but more like an expansion.
