-I don't find that big of a deal in co-op (in a game like this) so we'll see what they can do.
-I'd like to see more environments. I know it's Helghan and all so we'll have to see if you continue to play as Sev on Helghan or will the Helghast use the nukes (assuming there's more than one) and march right back to Vekta.
-I like the weapons and how they felt in Killzone 2, but some more weapons and weapon variety would be nice.
-There were a number of different kinds of Helghast forces, but how about even more?
-Improve lyp syncing
-Improve voice acting (ISA soldiers were hit or miss)
-Make the battlefields even more chaotic.
-More players in multiplayer would be nice, but have more maps of different sizes. If vehicles are added to multiplayer (assuming experience is otherwise similar to Killzone 2), then only for the biggest maps as I don't it would make much sense to put a tank in on anything smaller than a map like Pyrrus Rise.
-Better graphics with an always steady frame rate
-Rico needs to go.
