    Catch up to the rail car, shoot the wooden crates to pieces, then eliminate the marines behind them with the assault rifle.

  13. 13
    Jump off the ladder before the red laser alert. Enter the supply room for grenades and a first aid station.
  14. 14
    Exit the supply room, carefully pass the turrets. Quicksave where the track turns left.

    Run and jump over the track, then crouch behind a wooden crate.
  16. 16
    Push the crate left to shoot the marine at the sandbag wall with the .357.
  17. 17
    If crates survive, bash the nearest one and push the other towards the marine's wall.

Tips
  • When riding the elevator, crouch to avoid electrical damage.
  • Shoot the crates before engaging the marines to get a range advantage.
  • Use the .357 for quick headshots on marines.
  • Save frequently, especially before engaging groups of enemies or tricky jumps.
  • Use grenades effectively to clear out tripmines, zombies, and groups of enemies.
  • The AR grenade is useful for taking out distant targets like the sniper.
  • In section c2a2g, be careful not to hit the red laser alert while on the ladder.
  • When dealing with the mounted gun, jump to get a clear shot at the marine inside.
  • For the two marines outside, use C4 for an efficient elimination.
  • If playing the Source version, utilize the jump-crouch shortcut.
