A guy shared some password. He found it randomly in childhood. This password starts with 2615 chips. But! When you take the red lander the max chips do not increase. He also not sure if the game is possible to finish from this point. It was long ago. He said that it’s probably the one where there is no final boss. If you test this, then join discord chat and tell people how it worked: https://discord.gg/93C68CT or make a post on the forum: http://theguardianlegend.com/forum/
On the image below, you can see the password. And on the other one the coordinate of the closest red lander.
User Tishero on discord, reported that after beating the 10’s corridor the final one not appears. So this is unbeatable.
