Gears of War 3 - Forced Entry

There is a collectable that you can only get by successfully being stealthy in this section.

If you go slowly, you can usually sneak up on the enemy. If you tip them off, you can maintain your stealth approach as long as you don't allow any grubs to get near the giant horns in whichever area you are in. This section is just a strait forwards crawl. I recommend picking up the LongShot or OneShot (or both).

Head forward and clear the first area. You should have no problem taking him out before he blows the horn. The next area won't be quite as easy. The gate has two sentries on it; make sure you take out both as quickly as possible. Assuming you've done that, move to the next area and you'll have to do the same thing. The horn is in the middle this time so have to be a lot quicker in killing the sentries (of which there are two again). If you've failed the stealth run, skip to the next paragraph, otherwise a door will open to the right side here. Go through the door, open the gate and then take the lower path to the right. There will be some wild tickers running around. You'll come to a trough filled with meat and buzzing with flies. Near it should be two digger launchers and some COG tags on the ground. They can be hard to see because of the blood on the ground near the trough.

*If you've failed* once you've cleared the area of grubs, you'll get attack by a Corpser. You've got plenty of room to run around but you won't always be able to see the corpser when he comes up because of all the extra cover around here. If you can get ahold of a Digger, it'd be mighty useful here. Once you've kill him, head through the big gate in the back and the big door behind that.

You'll come to small area with a gate ahead. If you shoot the middle section above the gate, the wall will fall off and reveal the lever that will open the gate. Kill the two grubs up above as well. On the other side of the gate are a two level open area and some theron guards. They shouldn't be packing Torque bows just yet.

This is where the two paths meet up. If you failed, you'll be facing the entire area from an open area in the middle but if you succeeded, you will come in on the bottom level off to the right side. There are quite a few turrets around here. Clear the bottom level, then make your way to the top and clear that. You'll get attacked by reinforcement at this point but nothing too serious. If you can't proceed through the gate then aim towards the center of the area and blow that up by shooting the explosives caged in on the bottom floor.

The last area of this chapter is a little bit smaller with a turret. Clear this out and head up the ramp. Turn around and activate the lever to lift the gate.
