- A longuer sp campaing !
- Keep the ability to replay the level we want after beating the game (that really an excellent feature to replay the sp campain in the level we want)
- A little less on rail vehicule !
- More fighting sequence, Longer level in the same setting
- More of the special enemy, like the big guys with the machin gun, only one in kz 3
- Online Co-op with matchmaking (!!!) two player is enough i think
- Better transition between cinematic end and return to gameplay
- Bring back document and eamble like in kz2 sp
- Another level in the helgast jungle
- A level in a "paradisiaque" setting, green forest water blue sky 
- Full custom HUD in multiplayer it takes too much space in kz2
- For euro gamers, we absolutly need a server list with dedicated server allways online run by Sony with language name Server, because we dont speak all english in europe !!
- For matchmaking we need another option for language
- More maps at launch with the best kz2 & kz3 map
- All maps playable in all mode
- Single player dlc ? the gun fight is so great that just reusing asset to do a little single player dlc after launch would be really cool !
I cant wait to play killzone 4, hope you guys at the studio arent bored with killzone. But i hope you can do another game in another setting, your one of the top sony studio with naughy dog, so hope you can do what you want after killzone 4 !
-Ideally every class should have specific and vital team-based purpose, nothing for just getting kills.
-Prefferably make all classes able to use every gun, but change the abilities so that they will be balanced no matter what weapon you use. Or just add more guns per classes.
CLASSES (Originally thought of these classes NOT for Killzone, but its a good example of what I mean)
-Class 1 teleporter: Teleporter/squad spawn point. Melee finishing move: Warping space timearound the enemy with lightning, and teleporting the enemy away and the enemy reappears dead elsewhere.
-Class 2 engineer: Armor and equipment engineer/trap setter. Melee finishing move: Hacks and overloads enemy armor until it explosives.
-Class 3 hacker: Fast objective taking hacker/invisible assassin. Melee finishing move: Stabs enemies with an plasma power-saw combat knife, and rips out the hearts or spines of theenemies.
-Class 4 recon: Human recon scanner sees through walls/group shielder. Melee finishing move
tarting an energy shield inside the enemy's armor, and expanding it until it until the enemy isdestroyed.
Balance of classes:
-Recon class sees and defeats hacker class.
-Hacker hacks traps/sentries to defeat engineer class.
-Engineer has traps that disable teleportation and squad spawning of teleporter class.
-Teleporter can jam recon class's ability to scan and spot.
