Here are the things I noticed in Laxius Force: Heroes Never Die.
-If you actually defeat the Forbidden Dragon in the Pyramid, Kratin will do the same thing if you chose to run away. He doesn't even bother with the treasure.
-If you reach the third screen of the deeper Ruins of Metrolia. Random will state it's too dangerous for them and they will be forced to go back. Not to mention, everything's still there (chests, enemies, etc) in Laxius Force 3!
-The unreachable Yveen on the way to Modern Sciences is actually a copy/paste, which means that if Random were to talk to her, it would do the same thing for the Find Yveen quest.
-There's a actor called "NOTHING", and he has max all stats except for SP, and uses the Fighter01 graphic. His equipment includes Blessed Oak Blade, Balnuunla Shield, Balnuunla Diadema, Glacier Mail, and Golem Ring. Judging from all that, he's probably a test character. Oh, and he's also used for name inputing and item using. Almost every name inputing and item using typer requires an actor that runs it.
-There's an actor called "juli" and uses the sword enemy graphic.
-Also, there's an actor called Luciana, although she's unplayable.
-A lot of the items that would be used for the other two episodes were found here (Ketakeri Blade, Anti-Titanic Card, etc)
-There is a pig that the heroes can interact with that gives all of the party members 5 extra HP. You probably have to do it before you break the seal though.
-The map image is named "lp3mapb". I wonder if this was going to be used for Laxius Power 3...
-Golden Cocka-Cocka, Brussian the yellow, Askhbar the brown? Those may have been their original colors before they were released.
-North of Tyrine's town hall is some empty grassy space.
-When you defeat Power Caterpillar (optional tough boss) someone says "Where is Megatron?" Transformers reference.
-Baretta's shop is trademarked?
-The golden wasp has a 60% chance of running away.
-Also, what is that tower below the cliff where Random mentions he abandoned the Ulm-Warrior? My only conclusion is that they actually started somewhere around Metrolia Woods, and then went south, but there was no snowy forests. I wonder what happened to the TeAndal...
