You're meant to do two x5 combos in jungle with Dylan and Regina.

With Dylan it's at split 7, military facility 2.

With Regina it's split 18, south route 1.

You get 2700 for the raptors plus a 2k non damage bonus in both rooms.

I suggest either watching Kaladere's guide, which is pretty good even though he says it isn't, or just watching any top 10 run and seeing how they do it. One that has an input overlay is even better because you can see exactly what you need to do.

I suggest joining the Dino Crisis 2 speedrunning discord to get help quicker.

Oy thanks
