Clocks can be found hidden in a few places there Half-Life 2. But for whatever reason one melon is hidden in it Half-Life: Alyx and it can't be seen without actors use console commands.
As recorded in the latest video by Half life superfan MarphitimusBlackimus, there is one watermelon in between Half-Life: Alyx.
Things were very different back then Half-Life 2. In that game, released back in 2004, dedicated melon hunters can earn up to six watermelons throughout the game. And a few more for killing levels. MarphitimusBlackimus has made a whole video about these watermelons.
The new melon seen at the Alyx Games is a brand new machine, looking better than the watermelons seen on it Half-Life 2. Sadly, it cannot be broken into watermelons gibs. When it is shot it just goes unnoticed.
It seems that by 2020 the budget for watermelons will be reduced. Maybe one day Valve will update Half-Life: Alyx to bring replace the watermelons and fix this wrong. They go back and fetch the original Half life last year, After 20 years the game was released.
Just me I don't want to wait for a long time of my VR watches.
