Item description:

This map can give you 97% of all achivements in Half-Life 2.
Some achivements will be completed if you push the button, the others will you have to do by yourself.
I can�´t figure out how to make the last achivement, but all the levels in hl2 are being unlocked by pushing the button, so you can very easy coplete it yourself.
If anyone got an idea for how to make the easy solution for the last achivement, let me know :)

you have to extrackt the map to:
C:\Program Files (x86)\Steam\steamapps\wax54q8dab\half-life 2\hl2\maps
and then use console to open the map.
The map is called:
best_hl2_map_ever
I know the title is braging, i hoped it would be OK with you :)

Sorry for my bad english, hope you enjoy :D
