Walkthrough for semi-puzzle event Simulation Exercise in Girls' Frontline 2 (GFL2), stage 4.
You can either use the given preset units, bring your own, or mix them together. Can also bring friend support if you'd like.
Disclaimer: This event is deceptively auto-friendly.
My videos will only use preset units to keep 'em being followable by anyone. You wouldn't want to watch me blow up everything with level 60 dolls in a minute, would you?
Q: How are you accessing these already? Cheater! They aren't open yet for me!
A: Timezone differences. I'm not playing on Darkwinter server either. The video was recorded with English language toggled on at Haoplay, Korean server. Date change / daily reset happens much earlier over here than the English-speaking ones. At the time of this writing, it happened approx. 1.5 hour ago. No cheats or hacks were involved in making this video.
