Disabling Precursor Cannon?

[SlingBlade]

So something I've been wondering, is it possible to disable the Precursor cannon before the rescue ship arrives?

According to the wiki this was apparently possible at some point (last I checked) and there are even audio files for the Sunbeam where it isn't destoryed but is unable to rescue you. However even setting off for the weapon immediately after spawning and taking what little food and water you have with you the facility still declares you to be infected.

Was this something you could do in the early access that has now been removed/patched out of the game or is it still possible to disable the weapon at the start of the game if you get there quickly enough?

You have to beat the game before playing your radio messages. Once you cured yourself and start playing the messages they will turn back due to 'debris".
A word of advice, disable the gun BEFORE playing the radio messages.
Because if you play the radio message, than disable the gun, the ship still ends up getting blown to pieces because of a bug.
