How to unlock the Research & Development Coin achievement in Valkyria Revolution - Definitive Guide

See my guide on:

for a more comprehensive explanation of acquiring this expensive achievement.

Long story short, don't buy any weapons upgrades until you accumulate ~320,000 credits (I would primarily upgrade the core weapons of your team, for me being: the standard machine gun, the standard grenade, and maybe the standard RPG for tanks), which can be done in postgame on Chapter 10-1 to farm both ragnite and money. Once you have the necessary funds, save your game and spend away. Once you have this achievement, you can reload the prior save and be in the same financial situation you were in a minute ago, basically saving you 10+ hours of farming for the 300,000 kr achievement; you are welcome (assuming you read this before hand and did not make my mistake of spending, when I had the money, on secondary upgrades).

Sabancci & Co. is accessed by speaking with Basil in his Factory. Secondary weapons are developed by simply purchasing them with regular money. It will cost about 325k to upgrade all the weapons, and I would suggest NOT doing this in small increments as you go through the story. The money spent here does not count toward the "Golden Flower Commemoration Medal" achievement, so you'll be forced to do a lot of extra grinding unless you just save up all the money at once and then reload your save to keep it on hand to use for that achievement.

Use the same method as for "Golden Flower Commemoration Medal" to grind this out.

Do not upgrade until you have accumulated 320,000 crowns. Make a save on a flash drive, just in case. You improve all weapons, a trophy drops. Then you download from a flash drive and spend 300k on the promenade

Don't upgrade your weapons! During the course of the story game, of course, there will be a desire, you can pump up fragmentation grenades, a sniper, a shotgun, a bazooka, an assault rifle of one type, halfway, for example, or to the end if you really want to. But don't try to get this trophy, because... it is easily combined with a trophy for spending 300,000 crowns.
When you start grinding money and ragnit after completing the story, do not upgrade your weapons until you have accumulated 300 thousand. And then by making a save, you will be able to upgrade all your weapons and get this trophy. Load the game at a time when the money has not been spent and go to Promenad to buy the entire amount from a traveling merchant (he has the most expensive goods) and get another trophy, saving about 10 hours of tedious grinding!
