For anyone wondering SunBeam from CoSMOS has found out how to enable console cheats in bioshock remastered.
1 Modify the shortcut so it includes the startup argument -allowconsole
eg
"C:\Program Files (x86)\BioShock Remastered\Build\Final\Bioshock.exe" -allowconsole
2 Optionally downoload a cheats pack
LinkExtract the text files to C:\Program Files (x86)\BioShock Remastered\ContentBaked\pc\System
3 Start or open a game (the console doesn't work in the main menu).
4 Press tab and enter a cheat code
GiveAll
God
Exec powerup.txt
Wait until you pickup the ice plasmid in game before using the all plasmids cheat to avoid messing up the plot.
