Выкладываю статью на английском(нет времени переводить на русский), как с помощью бага стать бессмертным. Работает в код2 и код4. Но возможно(а может и не так) в код4 с последними патчами пофиксили.
HOW IT HAPPENED
I connected to a CALL OF DUTY 2 server and joined Americans and selected thomson. Autobalance switched me at the exact time I spawned, in other words, I got switched to germans when I selected my gun. That got me spawned LOOKING like an american, WITH a thomson but in the German team.
I walked around, realized I couldn't pick up guns, flags or anything. I ran out of ammo pretty quickly. So, I ran out in the field so I could die.
Waited. The americans surrounded me, started shooting. Nothing happened. The screen blinked red a couple of times, but nothing. I was alive. Nothing could harm me. Grenades, machine guns, sniper rifles... NOTHING.
Suicide commands didn't work either, so, since I was out of ammo, I spent the round spreading meelee attacks everywhere I was at.
Morale of story: ended the CTF round with 65 kills and 0 deaths.
HOW TO DO IT
Please, make sure you read the text mentioned above. It has valuable info for you before proceeding to the next step
I tried to repeat the process, and after many, many times, I made it. Here's how to do it (remember, the chances for you to get this right may be remote).
I joined the server. Waited for the AUTOBALANCING IN 15 SECONDS message to appear. Got a watch and started counting. Usually the team with less players is germans, so try joining the ALLIES team. In the gun select menu, select the gun EXACTLY when the watch completes 15 seconds. If you do everything with the correct timing, you should spawn with american guns and clothes, and if you press TAB, you'll see you are in the GERMAN team.
I know this is complicated, and I found it out by accident. But if you practice, and time this right, you'll enjoy it. Ah, remember to save your ammo, because you'll run out of it quickly. But it's extremely fun to spread out meelle attacks as well, since you should have about 10 enemies around you shooting from all sides and running away from you as you get close.
Again... you won't be able to pick up guns, pick up the ammo on the floor, get flags, etc... And the gunshots will still push you back. Using this at HQ guarantees you an instant win ;D
THE EASIEST WAY TO DO IT
You could either spectate OR keep playing until the autobalance message appears. Press tab, check which team will be balanced and quickly move to the team with the most players. If you are already in it, move to the opposite team and move back to the one you were on. Then, at the gun select menu, pick one when your timing reaches 15 seconds. Thats the easiest way to do it, and you will be 100% sure what team is going to be balanced.
You could also wait for the AUTOBALANCING TEAMS message to appear while in the gun menu. I'm not sure if this will work, but it should if you pick the gun almost immediatley. I'll test this soon
I want everyone to know that I'm very happy of sharing this with the public.
