Why do I get the feeling everyone is playing the game faster than me? I'm just about to exhaust all research from getting two Smuggler Negotiators and I've been at it for 3 months (with help of 100 brainers total). Geez.
What I'm doing is playing catch-up with Runts, upgrading whole fleet (decided on Fortuna, Triton, 4x Sabre, 2x Dragon, Devastator, Spector, 2x Thunderbolt or 2x Leviathan), upgrading armors, sorting equipment for all bases/soldiers as I finalize each squad specialization, and lastly - praying for that fucking Marsec Lasgun still. Just as I woke up today I realized I'll have to shell out over 50M for all tokens (mostly Jack) needed to convert into White Dragons. My hands are full even without research.
Not knowing of an easy way to reveal all missing research (not including locked out Codexs) I've been typing in commonly shared 3-letter strings into tech tree viewer to flush out unresearched topics. Pretty effective if not tedious. All that remains is figuring out where to get trigger items, which mission to accept and which to skip. Currently at 88% with Grey codex and hoping to reach low 90% after all is said and done. Then maybe unlock all Codex - for the toys and to achieve the holy grail of 100% faster than Dio can release new patches.
