In the wake of last weekend's home defeat to Johor FA and a 1-1 midweek draw with PKNS, LIONSXII, who will be playing in the Malaysian Super League this season, took an early lead when Shaiful Esah fired home a terrific free-kick in the 4th minute.
With goalkeeper Izwan Mahbud a virtual spectator thanks to a solid LIONSXII backline, V. Sundramoorthy's side maintained their lead until ATM bagged three goals in nine frantic second half minutes.
Venice Elphi Danny Kaya levelled matters from close range in the 51st minute, before Zakuan Adha fired ATM ahead from the spot four minutes later following Madhu Mohan's foul on Venice Elphi.
Following another Madhu error, Venice Elphi struck again on the hour mark to give his side a 3-1 lead.
Bloodied yet unbowed, LIONSXII once again took the game by the scruff if its neck and reduced the arrears courtesy of Agu Casmir's goal on 85 minutes.
In a sensational final twist, Casmir doubled his tally to snatch a draw when he headed home a rebound after Shahdan Sulaiman's free-kick had thundered back off the bar.
LIONSXII are now scheduled to play Johor FC on Wednesday at the Jalan Besar Stadium in Singapore.
