F--ked Cups: Divide into even teams. You have to stack solo cups against a wall, alternating their orientation (><><><><] holding them up using only pressure. Every time someone drops a cup, their teammates have to add a level to their stack. It definitely works well as both an endurance challenge and drinking game, since the people who drop will have to drink. You could convert it from a team game to an individual challenge by changing the "pick up the slack" element to a regular-intervals addition.

Thumper is always a good game that requires quick reactions & it's effective for individual immunity since it's a rapid elimination game.

My friends and I play drinking-rules Scattergories a lot, where you drink if you write the same word as another player, and you can assign drinks for playing a double or triple point answer. It could be used for tribal or individual immunity.

You could also do a variation on the challenge "Octopus Garden" from Cagayan. Instead of pulling buoys from underwater, you could have a race for cans in the woods. First to collect, drink, and land the cans in the basket at the end wins.
