Survivor, Season 435 (teaser trailer): The holocamera pans over the night sky, revealing an utterly unfamiliar set of constellations. A blur, familiar to viewers, starts to disturb the seeming peace of the night, and the characteristic blueshifted hyperspatial portal soon opens up, with the latest round of contestants for the Holovid-show Survivor bravely (or hesitantly) stepping through.
The world is stable within the habitable zone, has bacterial, archea, as well as plant and animal life. O2 and CO2 levels are such that the air is breathable (although a nasal filter might be a good idea). H2O can be tapped or gathered. The life-forms share Earth's DNA, left-handed basic structures, but have evolved under their own constraints and random events. No (known) ascended dolphin-level or above intelligent life has ever been found anywhere else in the Universe but Earth.
There are 150 contestants, distributed in groups of 30 at positions AI-weighted to be equally-(un)-favorable for Earth people. None are allowed any foreknowledge of the conditions on the world, besides likely temperature range. AI sentinels and force-casts are in place and will prevent potentially lethal dangers from engaging the Survivors before they get a chance to dig in a bit. Each contestant is allowed as many supplies as a light exoskeleton can carry (~ 200 kg net weight), although no recharge cells are provided for the exos. Allowed food supplies are capped at 60 days standard rations. No seeds, animals or any other non-vital symbionts are allowed through the decontamination filter.
Groups have a chance to tap out once every 604,800 standard seconds (one Earth week), in which case any survivors are rescued and eliminated from the game. Complete loss of all members will (naturally) also automatically eliminate a team. Last team left wins. If at the end of 53 rescue opportunities more than 1 team remains with living members on the planet, the number and strength of the health signals of the survivors are assessed and a winning group is declared. As per the standard Survivor contract, the winners get full land and mineral rights over the new world.
What is a good, potentially winning strategy of ensuring a food supply, in terms of adapting to identify and use edible variants of the local plant and animal life?
