some thoughts of mine and requests include...
Support streaks SHOULD be in the game, but no lethal streaks. ammo refill crates, equipment refill crates, things that really help the team.
Map editor, let us create maps.
Some kind of high end killstreak such as MOAB. My idea is a chemical bomb that kills all enemies on the map and leaves chemical gas on the map for 15 seconds so if the enemy spawns in they will die again. Also leaves an EMP effect for some time.This gives objective gamemodes a reason for this streak, giving you time to cap a flag or plant a bomb, ect.. (Also playing objective should go to this streak)
New killstreaks, keep your classic AC130 please just improve performance and audio.
The next Xbox said to have at least 8 Gigs of RAM so you can put extreme amounts of stuff in this game, give us 3x more options in killstreaks than we've ever seen before.
Better graphics./ Audio.
Complete character customization.
Great weapon customization including secodaries.
Way more weapons than we have ever seen.
Way more attachments than we have ever seen.
If not dedicated servers, then go back to COD 4/ MW2 connection style.
Good not corny campaign, but this is mainly about multiplayer.
Far larger maps with many players, again you will have 8 Gigs of RAM we can have more than 18 players.
Improved infected gamemode in which the infected actually looked like zombies. My idea for infected is to set it up like survival mode and have crates arouind the map to buy things. Kill more enemies and get more money, there is a killstreak crate to get missiles and airstrikes, and a weapon box to completely customize your infected killing loadout.
Chaos mode should return and updated for the new game. To add intensity, have intense music playing throughout the game.
All sorts of new features should be added to multiplayer giving us new experiences.
UAV should be harder to obtain, after all COD devs haven't realized that the UAV is actually one of the most powerful killstreaks in COD.
Tear gas and other equipment we haven't seen before.
More thought out maps with some above vantage points and bunkers for taking cover.
Give us maps we haven't seen like maps on the side of a snowy mountain. Or a Maryland state style forest map, in the fall time with beautful yellow and orange colors and maybe a little cabin in the center. Basically new designs, and not sucky cluttered maps with tons of buildings.
Allow for some killstreaks to be controlled by 2 players such as a adual chopper gunner or AC130.
Allow us to give our earned killstreaks to one of our teammates/party mates.
Give us some dark maps and also give us night visions goggles like COD 4. (Idea, dark swamp map).
If the game is a modern game, give us more drones. Use tablets like Black ops 2 to controll our killstreaks.
Idea for Equipment or killstreak, a little flying drone in the shape of a bug/insect that we can use to search out a camper/defender.
Killsreaks that makes sense, such as sentry guns that don't just appear in your hand. Maybe Sentry guns could be be chosen on a map and a chopper will drop 1 or 2 armored sentries in locations you designate.
Dynamic weather, something people want to see badly. This would go against my night map idea but instead some maps might be different time of day every time you play it.
I think I should stop here, I could go on all day. If any regular forrum reader actually read all of this, Thank you. But I don't expect that, just really want IW to keep COD extremely fresh and amazing.
IW, if creating a new engine and actually adding more features we've never seen takes a lot of time, please ask Activision for a few months more to create your game. I assure you that if you take the time to make the best COD yet, then people will not be upset. but if your use the same engine you've used for 5 years on a brand new console, COD will die. Good luck and I hope I am blown away by your next installment. Until then, I will be on MW3 & MW2 still. Bye.
