In
Sid Meier's Alpha Centauri (
SMAC), the
Voice of Planet is a
Secret Project. It may be built at a cost of 720 minerals, on discovery of
Threshold of Transcendence (E15). It gives +1 lifecycle to
native units subsequently produced at any of your bases. Also, once it's completed,
any faction may start production of the
Ascent to Transcendence Project. If you're playing with "Victory by Transcendence" as one of your win conditions, be prepared for a production race with rival factions.
How useful is this? At this late stage of the game, the mere +1 lifecycle is either useless to your psi-impoverished military, or just another cumulative bonus to be tucked away with those from the Neural Amplifier, Xenoempathy Dome, and other psi-oriented Projects. Either way, it's not likely to turn the tide of the game. It's actually a pretty poor buy, compared to other Projects in its price range.
