Kojima cipher broken by EG programmer

Eurogamer's lead programmer, Mark Kennedy, has broken a string of ciphers being tweeted by Kojima Productions, as you can see here.

Here's what's been published, followed by the cracked translations:

• "There is a shadow: lw olhv zlwklq xv doo." = "it lies within us all."
• "It consumes us. ju efwpvst vt." = "It devours us."
• "We cannot escape it, exlm px wxlmkhr hnklxeoxl." = "lest we destroy ourselves."
• "This shadow makes us who we are. Cn cm qy qbi uly nby gihmnylm." = "It is we who are the monsters."
• "Join me: fasqftqd, Xqgoaftqm, iq omz fgdz ftue iadxp fa pmdwzqee." = "together, Leucothea, we can turn this world to darkness."
• "But I can't! Ymnx btwqi sjjix rj, fsi ny sjjix dtz ytt." = "This world needs me, and it needs you too."
