Grand Theft Auto V, meet Half-Life 2. Half-Life 2, this is Grand Theft Auto V. You two should get along just fine.
This gravity gun mod for GTA V still needs a little work -- it's a bit twitchy in parts, especially with pedestrians -- but what's there is still pretty impressive.
Hopefully it works as well with whales as it does with cop cars...
The gravity gun mod was created by MatriZ, and you can get it here.
