Resident Evil 5 is antithetical to anything that I enjoyed about Resident Evil. It is not a survival horror, but a struggle horror where disparate game design ideas and tone clash impotently until the game turns into a soup of particle worms. Chris Redfield punching a big magma boulder is the standout moment of this game strictly because it is the one moment of comedy in an otherwise joyless and pough-faced slog.
If I had to play this without a friend it would somehow be even lower because the prospect of having to do some of these sections with a 2009 AI partner sounds nightmarish
