Questionable Ethics fight was hard, however because I couldnt figure out what to take as cover at first, but it turned out I had just to stay put where I came from and sniping soldiers one by one wasn
t a problem from there.
The only reason for tripmine part to be hard is source movement, but I found this part easier than in original, because it didn`t have guard and headcrabs. Anyway it was interesting lurking around there, taking it easy by exploring gaps in tripmine formations…
Surface Tension infinite soldier part is just ridiculous, because to pass this part I just had to perform kamikaze style rush by leaving grunt to fight against soldiers while not beign hindered at shooting down that flying thing, despite soldiers were just in front of me.
Anyway the hardest fight was the most annoying - that chopper at cliffs. Because to beat that fight you have to die as many times as it takes for you to figure out what to use as cover. And when that pile of rock is reached safe and game saved, there is still a lot work to do, especially when going after rocket ammo. I couldnt reach that box once without getting hit. Eventually as chopper was almost beaten, its attack pattern felt like increase in speed so gaps in defense weren
t enough to even reach rocket ammo box, so I retreated in backroom where I had carried rocket ammo prepared before fight. Luckily it was enough and chopper went down only after taking mere 25 rockets, on hard.
