Any tips for VR mission 17 ?

[Xolaroth]

I always wanted this game so I got it on PS now. I have already completed missions 1-16 and 18. I can get through the first 2 areas fine but the last area with the gekko and raptors seems random. Any tips/ tricks/ strategies for any part of this mission would be greatly appreciated.

 

Edit: I entered the final area with rockets and grenades, stood back to not alert the gekko and shot rockets at the closest raptor until it was stunned. I then switched to my grenades to finish it off. The other raptor went berserk and I changed back to my rocket launcher. I shot the Gekko which was still not alerted and stood in a grenade pile to spam it and the berserk raptor until the gekko died. The raptor was stunned so I stood on the rockets and aimed to not miss and shoot through its legs. I finished the remaining dwarf gekko and got a time of 3:16.86.
