And the tip is in the mod title: Aliens: Isolation. Creative Assembly's Alien: Isolation has been out since 2014, but according the mod-creator, Matt (love a good mod handle), the original game was "too easy", as reported by DSOGaming, which prompted him to up the Xenomorph ante.
Our very own Kosta Andreadis is already hiding in a corner somewhere after watching the below teaser. There's no release window just yet, but as DSOGaming points out, the mod will stay in line with the original game's mechanic of playing hide and seek rather than being able to kill any of the aliens, so yeah, this might be one of the scariest additions to an already intense experience from a survival-horror perspective(s), and we're keen on it.
Watch the mod teaser embedded below.
