When ever i need to use a boost whether it be a vortigaunt boost or a grenade boost I never get enough height. In the blasting chamber I previously used the strat where you jump on the vortigaunts head and wait for him to attack. but i had to save and load literally 30+ times on average and I only managed to get the jump a very small percent of times. Im pretty sure my timing wasnt off and I only ever JUST made it to the ledge. This applies to grenade boosting also, i can never get the height that I see other people get. Is there something I'm missing to make me get higher? (I'm playing on easy difficulty)
