Despite taking the lead through Nicky Ajose, Town were pegged back and fell behind before Obika struck late on to earn the visitors a share of the spoils.
Mark Cooper was forced into making changes once again – with Wes Thomas picking up a hamstring injury last time out against Colchester, James Brophy was drafted in at left wing-back as his replacement. Fabien Robert formed part of a front three alongside Nicky Ajose and Henrik Ojamaa.
The hosts had the more clear-cut of the early chances – Keshi Anderson volleyed over from a wide position before Jordan Williams reacted wonderfully to deny the same player a shot at goal from a good position.
Meanwhile, Henrik Ojamaa fizzed a left-footed shot wide after being picked out by Ajose before James Brophy made space for an effort at goal but only drilled it straight at Thorsten Stuckmann in the Rovers goal.
Perhaps the best chance for either side fell to former Town man, Andy Williams. Picked out by James Coppinger at the far post, he could only send his header wide of the target.
Town made the perfect start to the second half. Ojamaa’s lofted pass was weighted perfectly for the run of Nicky Ajose who sprang clear of the defence before lifting his shot over the goalkeeper and into the net.
Moments later, the frontman had a glorious chance to double his and Swindon’s tally but, after being set free down the left, he could only put his shot straight at Stuckmann from a wide position.
Louis Thompson then drilled a shot off target after Stuckmann had punched a cross out towards the on-loan Norwich man.
With fifteen minutes to play, the hosts levelled the match through Keshi Anderson. Picking up the ball in a position on the left-hand corner of the area, the frontman curled a shot beyond Ty Belford and into the net. Just with Town’s opener, the hosts could have doubled their lead but Dany N’Guessan was brilliantly denied by Belford.
Just minutes later, the home side did take the lead thanks to a penalty. James Coppinger was tripped in the box and former Town man, Williams sent his spot-kick low to Belford’s left and into the net.
However, with time running out, substitute Jon Obika met a corner and directed a header into the back of the net to earn Swindon a share of the spoils.
