As we know, in Keen 2, the Vorticon mothership was
The destruction, as we know, would have been viahovering over the Earth, ready to destroy all of Earth's cities and wonders
The wording of the story strongly suggests Tantalus rays being city killers (otherwise, much of it would be redundant). It is possible to interpret it otherwise - but it would probably be worse than most biblical interpretations.eight X-14 Tantalus rays in the Mothership, each pointing to a specific city on Earth.
Evidence for world killers:
When Keen "accidentally" fires off a Tantalus ray (or, alternatively, dies before completing his mission), we are shown clear visual evidence of the entire earth being blown up via a single Tantalus ray.
So, let's try and settle this the democratic way (since we all know science by democracy is most valid - just think of the flat earth!). Under maximum power, are Tantalus rays world-killers, or city-killers? Should the game over sequence be considered "more" canon than the storyline, or simply dramatic license? Any kind of creative reconciliation is welcome.
