Gears of War 2 Guide - Act 1: Tip of the Spear
Chapter 1: Welcome to Delta
At the start of the game you're given the option to run through a few training exercises, though you can skip the training entirely and jump right into the action. However there are several benefits to choosing the training route. Firstly, the training session is very brief and will serve to familiarize you with the game's basic controls and combat manoeuvres. Secondly, two of the 41 total collectibles in the game are found in the training area. Lastly, completing the training session unlocks the “Green as Grass” achievement.
Collectible (1/2): Select the Training option at the start of the game and walk to the end of the alley once in the training area. Here Jack will continuously saw at the chain link fence until you take cover. Look for The Eagle Newspaper on the ground a few steps across from the dumpster and wooden fence in this area.

Follow the instructions that appear onscreen and eventually you will come to a ladder, which marks the end of the training session. There is another collectible nearby, so don't start towards the hospital just yet. Slide down the ladder, turn right, and enter the garage there.
Collectible (2/2): Upon entering the garage, turn left and make your way towards the desk at the other end of the room. The collectible (Ambulance Driver's Log) is on the floor in front of this desk.

Once you have the collectible, exit the garage and head for the hospital in the distance.
