u/Iamnotvivi

so this is my 1st time doing any game on hardcore and I'm at G stage 2 and only have 40 bullets, hand grenade, flash bang, and a knife and im on caution for my health any tips to get passed this? or should I restart the game from the beginning?

Edit: Thank you so much to everyone for the helpful advice because at 10:49pm I finally managed to defeat him
