Very hard. Capcom Quest of Umbrella Corps. Another co-op competitive attempt in Resident Evil series.
For God's sake, Capcom!
I think the only thing I can praise is the stages, it's always great to revisit classic places from the franchise.
I didn't play the online mode because no one is playing the game, but I think it's not very different from the offline mode "The Experiment".
In short, there are three objectives: Collect DNA by killing zombies, maintain position and find all the suitcases. Nothing too complex.
I found it easier to kill enemies using the melee attack. But on the other hand, the enemies kill you with two or three attacks...
Anyway, the good news is that the next game in the franchise would be responsible for a new era for Capcom.
