Apologies if this has been mentioned, couldn't find it in the search.

I just finished the church level and there's a cloaked Ceph in the basemant. I tried to shoot them but they ran away, is that some hidden achievement or easter egg or something? I can't remember seeing any other cloaked ones in the rest of the campaign bar the ending?

I couldnt kill him either no matter how fast i ran. I am curious as well

Their appearance is just foreshadowing for the last level, you can't interact with them, at least I wasn't able to. I think I saw about 4 total. In addition to gate keepers, there's one in the burning building part, one on top of a cliff you can't reach, and I think one more but I can't remember where.

reminds me of the BOBs in h:reach.
are we REALLY sure they can't be killed?
and could you please post the location of all bob-cephs you found so far?
i be hunting now.

ah. just when i was about to enter the basemant of the church i remembered seeing that guy to, you clearly can't miss him.
too bad you can't shoot em, even on supersoldier, because i love the taste of eastereggs.

Even if you could kill them it doesn't give you enough time they are insanely hard to kill. Not to mention you get 5000 nanites for killing them.

the Guardian class Ceph can be fought in the last Level, incredible amount of armor and cloak, each kill gives a huge amount of Nano catalyst (5000), they should have put more of those as a challenge ...

another location to find them, New York library (burning in flames), you can spot another one there, stalking you

yeah i did it,i'm awesome i've killed 2 guardian class ceph in the middle of the game(NOT IN THE END!!!!) it is possible but until now only one will give u 5000 nano-catalyst,

the first one was on Gate Keepers,in the end when u enter the room with the stairs dont walk to him,just stop at the entrance and enable nanovision,if u see him just shoot him with K-Volt and start walkin to him (dont stop shootin ,keep shootin in one burst shots)when u are right near him shoot one last time at him then go behind him activate cloak the stealth kill him...taddamm,the he is dead lying on the floor,cloaked and u wont have the 5000 nano-catalyst.

the second one is on the level that u meet hargreave for the first time(the level after Dead Man Walking)the guardian Ceph is in the building that u see 2 Guardians when u leave the EMAT evacuation site(u cant kill those )so when u are in the building and there are ticks all over the place enable visor and tag every enemy that u see (never disable Visor!!!!)but when tagging be sure that u know what u are tagging(for example if u are tagging ticks it wont have a profile data in the left ,but if u tag a Guardian Ceph it will have one) when u are on the second stairs of the building (the entrance stairs does not count) cloak and look for one untagged enemy,that will be the Guardian then u can disable Visor ,but dont disable cloak!!!!! just pass trough him without being right in front of him(go next to the right wall still cloaked) when u are in the stairs u can decloak so u can recharge but dont gon on till u are recharged,the cloak again and go trough the stairs,in the end of the stairs enable nanovision just so u know whats is his position then throw a grenade at him,he will run to the stair that u r on then go behind him and stealth kill.(decloak before throwing grenade) Now there he is in th floor dead UNCLOAKED AND U CAN COLLECT 5000 NANO-CATALYST!!!!!!!!!!!

i figured it out myself ,and im here posting this just so i can help....in other words im awesome!!!!!!!!!!!!
HEHEHehehehe XD

Nice one man have to give it up to you!
===*Spoiler*=====
But did you notice In the end when you run into all those Guardian Ceph if you look behind you
The Predator Is behind you with his laser beam aimed at your chest!?!?!?! CRAZY!!!!!
Only kidding of course.lmao

thx man

Crysis BoBs, huh?
Has anybody tried hitting them with JAW rockets? I'm sure if you lobbed a frag and shot the rocket as the frag detonated, you could kill the gate keeper. Presumably they drop something beyond nanites.

they can be killed, according to page 1.
haven't tried it myself though. c2 has been replaced with reach again. even though crysis2 gives me a IMHO better "spartan experience", bungie kicks crytek's ass big time, when it comes to creating a "space opera", filling their game with details other than throwable objects/eastereggs (ie BoBs), community support, MP balance, community support, server stability, matchmaking, community support and community support.
i'd rather "support" bungie by playing their game in MP than a company that behaves like crytek.
plus, after almost gettin accustomed to the crappy connections in C2, reach MP makes so much more fun!

Yeah, I've seen Crysis 1 and the boss in that game, was pretty dissapointed with the bosses in this game, I didn't feel achieved when I killed them.

Agreed. Also Crysis 1 was Wayyy better like you had more Area to Explore like Farcry 2. C2 is very narrow.

@kabrita - nice post I will try that out, i wish they put more Guardians to fight, they are so fun with cloak on...

thats 5000 is real handy when trying for the first time otherwise i got 200K of useless NC
