In campaign, we face against enemies who are armed with level 2 or 3 heavy railguns, which are over-kill and can kill the human player in single shot from full health.
I know It's challenge, but It's kinda way too much punishing, even on easy difficulty. Especiality when you enter a very wide arena and those railguns can shoot you from off-screen without giving you chance to fight back (mostly because you dont know where they are located.).
Flanking them doesent really work, since they instantly start aiming and shoot at you in mileseconds. <-- this is not only the case with heavy rainguns, this issue is also with BNG's and a good upgraded rocket launchers, considering the fact that you cannot reflect those projectiles.
^ this causes really frustrating gameplay in my opinion, It's just the same shoot and peek to cover back instantly fast all over again in almost all levels, It's boring and frustrating at the same time. There is not really much a wide open of tactics options in the singleplayer campaign, It's just using the same most effective tactic all over again and again, aaand again.
What are your opinions about that, and do you think there can be a solution to this?
