Michael Pook struck in the fifth minute of added time as Cheltenham staged an astonishing comeback to beat Burton 6-5 at the Pirelli Stadium.
The midfielder's hat-trick goal came after the Robins had trailed 5-3 with only five minutes of normal time remaining..
Burton flew out of the blocks to take the lead with just 70 seconds on the clock. Shaun Harrad seized on a Steve Kabba flick before drilling a right-footed shot inside a post from the edge of the area.
Only a superb finger-tip save by Scott Brown denied Harrad a second goal with a 15-yard volley in the 23rd minute as Cheltenham's poor marking was again exposed.
Harrad continued to torment the visitors' defence and put Burton further ahead from the penalty spot in the 32nd minute after being tripped by substitute Lee Ridley.
The striker's third goal might have soon followed, but he fired wide from a Kabba cross and the Robins came roaring back to wipe out Burton's lead with two goals in three minutes.
Justin Richards applied a close-range finish to a David Hutton cross in the 53rd minute before Medy Elito hammered home an equaliser from 20 yards.
But Burton were back in front in the 58th minute when visiting skipper Michael Townsend turned a Cleveland Taylor shot into his own net.
Kabba appeared to make the points safe for the home team in the 72nd minute after Cheltenham failed to clear Harrad's cross, but Pook gave the visitors renewed hope when he drove home a 20-yard free kick in the 84th minute.
Kabba struck again from close range a minute later, but the Robins bounced back in stunning style.
A deflected Pook shot and Richards' second goal put them level before the midfielder smashed the winner with a right-foot volley.
