During matches of Dino Survival, you slowly work your way through waves of dinos at different points.
At one of the later two points (generally the last one), a large Dino will spawn.
It’ll either be a Carnotaurus or a Triceratops.
When it’s a Triceratops, you need to be playing as the tank Exosuit called Roadblock. You can either start the game as Roadblock or switch partway through (I switched to Roadblock the second I heard the Triceratops spawn in).
You switch by pressing
, selecting the suit you want and then pressing
.
After a few seconds, you’ll be able to enter your selected suit by pressing
+
Once you’re the Roadblock, watch and wait for the Triceratops to back off a little. Then it’ll begin to charge. Make sure you’re directly in its charge path and press and hold
to pull up a Reinhardt-style shield.
As the Triceratops charges into you, you’ll clash and hold it at bay, stopping the charge.
This achievement should then unlock.
