The Extractor is the marine resource tower. The commander places it on a free resource node. Once built it ticks every 6 s, giving:
- 1 team resource (for the commander), and
- 0.1 personal resources to every marine on the team (except the commander).
So each extractor is worth 10 team res and 1 personal res per player per minute. More towers mean more of both. See Resources for the full economy.
Defending extractors#
- Extractors need room power: an extractor in a room whose power node is down collects nothing. Killing the power node is a cheap way for aliens to shut off an extractor.
- They have a lot of armor (1050), but a skulk biting one alone will still kill it.
- Mines and a single Sentry can buy time; observatories reveal skulks sneaking up.
- The commander gets an alert when an extractor is under attack. Respond fast: a dead extractor costs 10 res to replace and loses income while it is down.
