Maybe it's just me.... but I'll go with level design. Eg.
Stack of wooden chairs blocking your path.
Rocket launcher not being able to blow a hole in a wooden door. Hell in anything, but I'll give them a pass for everything else. But come on!!! I need to get a key when I have a rocket launcher equipped?
Red barrels with conveniently placed enemies around them.
Indestructible cover.
Regenerative health (this is not level design per say, but taking health management out if games is what I feel to be one of the biggest flaws modern day gaming has inherited.
