Cheat Engine

FFS, this game actually encrypts variables like health and ammo in SINGLE PLAYER mode

And debugging is also a pain in the ass.
I did manage to get godmode to work(Sadly enough I can't provide a script or pointer as you need one piece of experimental software I don't want to release just yet), but damn, these guys really didn't want people to use cheats for whatever reason.

Perhaps when a cracked version comes out with integrity check disabled I'll provide a script for inf health

anyhow, 998e20 contains a decryption routine for variables. Perhaps it can be useful to someone.
esp+4=pointer to encrypted data
esp+8=destination of decrypted data (initialized with the encrypted copy)
esp+c=number of bytes of the data

Integrity checks are checking the values too? They usually check the codes only. How is it detecting if we use a pointer?

I guess they have used dynamic variable for encryption. If they put so much effort in it.

Why don't you just bypass the integrity check?

no, the integrity check only checks the code

Problem with finding the integrity check is that the thread responsible for the integrity check relies on all 4 debug registers to be set properly (on exception do something)
Also, the integrity check only happens when doing something in the game, like killing 5 orks in a row
I might know one other method to find out the integrity check routine (make a part of the code that is never executed inaccessible and watch for an exception) but I haven't tried (or implement that in ce) yet

Right now i'm making use of a combination of an updated version of the stealthedit plugin and dbvm (since i'm on 64-bit) to do the code injection

Also, I haven't figured out where exactly health is stored in a encrypted way (I'm currently basing my godmode on the routine that handles when you get hurt and health is already decrypted and placed on the stack there)

Hey it sounds fun. Smile

I just love protections. It's so boring when you can hack a game in 5 minutes without a single crash. No challenge at all.

Hope they didn't screw up the game too badly. For God's sake, I don't ask for too much, just a little WH style massacre with +2000 enemies / level.

EDIT:
Oh yeah, forgot to say, I need that god mode because I suck in FPS games. But if it is working, give me that +2000 enemies. And unlimited ammo... Or a good melee weapon. Like a chainsword...

I simply modded this game to my liking.

Do you mean like ini/cfg file editing or some more complicated stuff?

Dark Byte · Posted: Tue Sep 06, 2011 10:27 pm Post subject:

That game came out 29-hours ago (And yes, the demo was easy to edit, but the released game is different)

Anyhow, just finished it and it's an ok game. (Not great, but ok)

It has lots of enemies at once and several different kinds of weapons. If you have played the RTS games you know what to expect from them. (Bolters, energy weapons, hammers, axes, chainswords, etc..)

The buildup is pretty much like any wh40k campaign: Orcs attack, space marines come to fight them, discover chaos is present as well, fight orks and chaos, chaos leader turns into demon, demon dies, the end

There's also some minor plot stuff you can pick up along the way (recorded audio messages)

Downsides:
As most fps games these days, there is no choice. You just walk along one path and occasionally take a turn

You can not rebind keys during gameplay. You must quit the game and then change the keybindings

No other races

Only one planet (a construction planet at that) so constantly the same kind of environments.

if you have slow reflexes, like take 3 seconds to move from one key to another one, you won't be able to finish the end boss battle as it's one of those horrible console "tap keys in right order and speed to win battle" sequences

----
I do not recommend you Buy this game right now, but if you wish to play in co-op wait a month for the dlc that adds that. The price may be a bit lower then as well

Well it looks ok from your review. I didn't play the demo so I had no clue about it. I never wait or expect any game because I am always disappointed. I look at them when I see they are released yet.

@Dark Byte

Will you post the god mode script?

For some reason, the demo did not work for me. But I got the cracked version and it seems it doesn't have an integrity check.

It isn't a problem if you don't post it, then I do it on my own anyway. Maybe the codes that you have posted will work me too. Will check it now.

i seem to have forgotten to save my corrected auto assembler script after finishing

and it was an script after enabling stealthedit and runtime editing of the script to see what offsets worked, but it might be useful to some minor extent

Ok, thanks. Now I think I will finish it first on easy without cheats, then see if I can adapt this script and check if it has any memory checks.

Since you'll be sucking the life out of your enemies for a while check out http://forums.steampowered.com/forums/showthread.php?t=2109002 on the subject. Made me laugh

Haha, really. I get the idea to force you to do beautiful executions all the time (while you are unprotected and enemies can beat you to death), but even the "auto-healing" makes more sense. I guess they are secretly Berserkers of Khorne. Blood for the Blood God! And the chainsword sure spill lots of blood.

Btw. who would want to stay alive when every death is rewarding you with one of my favorite fanatic quotes.
It is better to die for the Emperor than live for yourself.

Space Marines are the perfectly brainwashed soldiers. Smile

Finished. What a happy ending. Just as I expected.
