Former Fulham man Dempsey stunned the Black Stars after just 29 seconds when he latched onto a pass from Jermaine Jones, skipped beyond John Boye and coolly fired a left-foot shot across Adam Kwarasey into the bottom corner.
It was a huge blow for Juergen Klinsmann's men but they responded with true grit and won it on 86 minutes when substitute Brooks nodded home his first goal for his country from a corner.
PRE-MATCH: No Boateng or Essien, but Gyan starts. Ghana line-up without two of their star names, former Chelsea midfielder Essien and Schalke playmaker, Kevin Prince-Boateng. The USA go with a strike pair familiar to Premier League fans in the shape of Ex-Fulham attacker, Clint Dempsey and Sunderland's Altidore.
1' - GOAL! USA 1-0 GHANA. The US strike inside 29 seconds! It's Clint Dempsey. The ex-Fulham man picks up a pass on the left, slaloms past his marker and coolly fires into the far corner. Incredible start!
15' - GHANA CHANCE! Superb goalkeeping by Howard who dashes off his line to thwart Gyan after a slide-rule pass from Christian Atsu parted the USA defence.
19' - USA CHANCE! A good move down the right sees the ball fall to Altidore who crashes his shot into a defender when he looked certain to score.
21' - INJURY. Altidore chases a ball down the line and pulls up clutching his hamstring. It could be curtains for his World Cup.
45+5' - GHANA CHANCE! A Ghana corner right at the death, but it's easily driven away. The USA mess up their breakaway though and Atsu feeds Andre Ayew who scuffs his shot from 10 yards with the goal at his mercy.
56' - GHANA CHANCE! A great ball in from the left finds Gyan unmarked but the striker plants his header over the bar. Gilt-edged as they say.
82' - GOAL! USA 1-1 GHANA. Ghana are level! A lovely move down the left sees Gyan back heel into the path of Andre Ayew who fires a lovely effort beyond howard at his near post.
86' - GOAL! USA 2-1 GHANA. USA are back in front! John Brooks rises to power Zusi's header into the net. Bedlam in the stadium!
Can the US upset Portugal? This game was seen as must-win in the context of a group containing Portugal and Germany. The latter look all-set to top the pool following their impressive demolition of Cristiano Ronaldo and co, and if confidence is low in their camp, this spirited US side could yet take advantage to sneak into the last 16.
Clint Dempsey’s goal (29 seconds) was the fifth fastest in World Cup history.

MAN OF THE MATCH
Geoff Cameron (USA): It could have been any one of half a dozen US players who gave absolutely everything, but Cameron was a rock throughout and made some vital tackles and interceptions as Ghana probed for most of the second half. Superb from the Stoke City man.
