yeah that part was crazy and I hated the infinite enemy re-spawns. Luckily I was able to push forward pretty fast so it only took about 20 trys to clear the whole section. lol. Personally, I had the hardest time on the final tunnel in "Burn Em Out". Retried soooo many times until I realized I would have to restart the level to save all of my smoke grenades for that part. I only had 1 smoke grenade the first time.
Your absolutely right that the game is 10x harder (cheaper) from the unfair number of grenades thrown at you and its easily the most frustrating Platinum I've gone for.
