You can pay credits to Respec in the medbay and you’ll regain only the default amount of skill points you should have for that level. Reloading a save after using the cheat leaves you with 0 skills, 0 skill points. Unlimited Skill Points works – but if you reload a save, you not only lose all of your leftover unused skill points, you lose all of your skills as well, even ones you bought prior to using the cheat. Something to keep in mind for people having issues! I noticed that any time I bought things, the credits were depleted as normal, but if I sold something, it went back up to 10k again. Unlimited Credits works as advertised – if you sell something, it bumps your credit amount up to 9999 or something like that. I messed with this trainer a bit today, although only two of the cheats.
