10 Easy Ways To Get Impossible Video Game Trophies
10. Zombie Chopper - Half Life 2
In theory, Zombie Chopper doesn't sound like a difficult achievement. It dictates you need to get through Ravenholm by only using the Gravity Gun, and anyone who's played through this level no doubt remembers all the traps and items you can throw at your enemies.
Only, once you get onto the roofs, these helpful pieces of detritus basically vanish, leaving you to parkour a desperate path away from your bloodthirsty foes for half of the whole level.
However, this can be gotten around with a little sharp thinking, and the frustration from trying the level like five times and getting your face eaten in each one.
The best method fans have developed for this is to carry Dog's Ball through the entire level. Not only can this distract enemies from you when fired, it can also attract all nearby enemies towards it, meaning that you can launch it into a room, clear up what would have been a series of sneak attacks, and then grab the ball to leg it your way through the next portion of the stage.
