If this is on Steam, have a look at the redeem FAQ page that outlines what you can do. Especially the section regarding "Invalid key"; which states: If you are still receiving an invalid error, we encourage you to contact the retailer for further assistance. If the retailer is unable or unwilling to assist you, it is recommended that you contact the game's publisher for further assistance. If none of the above helps, you're probably out of luck. Thankfully Crysis is often on sale on places like Steam and GoG for cheap.

It seems there are a few forum threads out there dedicated to this. The only success I've found so far is for Windows XP, here.

I once searched for the same thing, and I couldn't find anything like that. So my answer is no, there aren't any mods for this (at least as of now)

Someone else seems to be in this position, judging from this post on the Tech Support Forum. The answers from the site moderators indicate that you can't legally download these. If you do not have the English pak on the CD like Koala said we wont be able to help you as it will infringe on EA's copyright agreement. and Yes, there are different DVD's of the game with different contents (language pack), each DVD has a license agreement. So If you have a DVD from Australia and send it to Turkey but the Australian version has no Turkish language pack you are unable to alter the game due to the license agreement as it will be altering the original copy which resides on the DVD.

Crysis Warhead isn't a multiplayer component. It's a fully single-player game in fact, telling the story from the viewpoint of Psycho, with in my humble opinion better gameplay than the original. You're talking about Crysis Wars, which is a separate game bundled with Warhead, as its multiplayer component. This is in contrast with Crysis where the multiplayer was integrated. I would say getting Warhead is definitely worth it to add to the story and have a multiplayer game.

Sorry to bring up an old thread, but there is some missing information from Lokuzt's otherwise perfect answer. Quoted from the Wiki(link)... "After collecting all data pads in Crysis 3, a new file appears that states that Nomad is alive and is being hunted by a Nanosuit operator known as "Lockhart." Although exactly which Lockhart this refers to--the deceased Commander Lockhart, his apparently dead nephew, or a new character--is unclear." Hinting that Nomad somehow survived the rocket attack and is still operating in some capacity.

Walking gives the maximum distance availabe while cloaked in a long time, running gives a moderate distance while cloaked with the normal speed at a moderate time, Sprinting gives the shortest distance at high speed at a short time. So depends on your situation and what you want to do and choose. I Finished Crysis 2, there sprinting takes away much more energy, even while not cloaked And I finished Crysis 3, where Sprinting takes no energy without cloaking, but while cloaking, I noticed sprinting taking slightly lesser energy than it's prequel.

As user98085 have already pointed out, this adds simulated inertia (delay on movement) to the weapons. However this really is just an aesthetic detail, as bullets will still instantaneously fly to the center of the screen, as illustrated by this video by aucoorslt on YouTube:

The same thing happened to me. Went smoothly more or less until that point, but the frames per second went down to like 0.5 on that last level. Completely unplayable. My solution was just to lower all the graphics settings to minimum / close to minimum levels. Yes, it sucks, especially in such a beautiful, climactic battle - but I was hardly able to move otherwise. When it was low enough I was able to play through that battle relatively smoothly. When I played the game my system was greatly inferior to your current system, so I suspect you could make do with just medium settings.

You need a missile launcher. There should be a launcher in some room on the 1st floor, and I also think there's one on the roof. I'm pretty sure there are additional launchers lying around, maybe in other buildings. Be aware a tank takes 3 missile hits to kill. Just shoot and run away until it's down - don't remain stationary while shooting all 3. The tanks should appear in your minimap.

The "very high" option is only available on a DirectX 10 capable operating system (Windows Vista/7) with a DirectX 10 capable graphics card. Your graphics card is DX10-capable, but you would need to upgrade to Windows Vista or Windows 7 to use DirectX10-only effects. There is an inofficial way of enabling most of those effects without using DirectX 10: Guide on how to enable "very high" settings on Windows XP. There is no official ultra-high setting, but there are a number of additional tweaks you can apply, some of those are listed in the guide I linked to. But your 8900GT is probably not powerful enough to run those kinds of settings at high resolution and anti-aliasing.

I had exactly the same problem. Alter the hz rate of your sound card. (its in the audio properties of your PC, not Crysis itself). Its under the advanced tab. Try setting it to 16bit 44100hz. If it is already that, just change it up one or down one. Worked for me.

I appreciate all the useful info you guys have posted there. Here is what worked for me: Un-installed the game completely Install with minimum option (no additional languages, no punkbuster) By default, the shortcut to the game was using the 64bit version of the game, use the 32bit version instead. And Voila! The game started working again. I hope this helps someone

Preamble This 3 years old question bothered me much more than it should have. The theory While it was not a certitude, I was pretty certain that guards would leave damaged vehicles. I was also pretty certain that there were no viable non lethal-options, apart from simply avoiding combat, which is mostly doable. From your mission's objective, the area seems to be the facilities neighboring the open-pit mine in the mission "Awakening". Let's put this in 3 points: Is there a non-lethal option that permanently disables enemies ? No. Even punching is lethal. What about the tranquilizer (aka "tactical attachment") ? Worthless, as it keeps a guard asleep for maybe a minute at best. Can we force guards out of vehicle ? Yes, by damaging said vehicle in a manner that would be considered inoperable or unsafe. "Inoperable or unsafe" Guards leave vehicles that are damaged to the point of being about to explode. In such case, there is a chance that the guard may not leave fast enough and die. This can be done by shooting the vehicle's reservoir or attached jerrycan until it catches fire. That's the unsafe way. Guards will also leave a vehicle that is damaged in a way that makes it impractical to drive. Considering the limited damage model of available vehicles, this is essentially a matter of missing tyres. What comes after the theory I reinstalled the game. Copied my archived saves. Loaded the right level. Made my way to the quarry. Climbed back on a beloved roof spot. And I shot a tyre to make a KPA soldier disembark a vehicle. This last part can be seen in this video: Which I summarized in this picture: And as far as punching a guard manning a gun on a jeep, well, what can I say to that... Conclusion You have to kill them. Kill them all. No KPA soldier leaves that quarry. Or in other words: "No, there is not a non-lethal way to disable guards in vehicles". Note Played on Delta difficulty, of course.

I felt the control behaving in a very similar manner when i played Crysis. At some point in the single player campaign towards the end the afterburner didn't seem to do any favor and the controls barely responded. But that only seemed to be the desired effect from the game developers' standpont, a kind of overwhelming effect created by the growing sphere and the sudden climatic changes created by the alien's insurrection. Even some of the game guides said you will have to go through a frustrating loop of dying and respawning till you get lucky. I lost track of the count of times I respawned till i got lucky enough to find a better direction/path. I guess it's the same case for you!

I've discovered at least two types of auto-aim in Crysis/Crysis Warhead. The first takes effect when switching into aim mode. It just jerks your reticle toward the nearest nearby target. The second type takes effect when firing. It's like a sort of magnetic attraction that dampens recoil drift -- very noticeable with automatic weapons. Anyway, both types of auto-aim can be disabled via CVARs! Set aim_assistAimEnabled and aim_assistTriggerEnabled to 0. If you bought Crysis through Steam, add these to your launch options: +aim_assistAimEnabled 0 +aim_assistTriggerEnabled 0
