Play as Kate Wilson during the Great Population Flood and take on the terrorist group the Malthusians in a Tomb Raider-ish game with action, puzzles, climbing and amazing water effects.
The Hydro Engine was designed for Hydrophobia to create realistic water effects as you find your way through epic linear maps completely flooded in water. Kate even wields an interesting physics water gun with unlimited ammo cool down. This makes for some interesting puzzle solving with the surroundings.

Hydrophobia is a pretty short game, but full off action and crazy waves of water everywhere. Proton was able to handle this 2011 engine without any serious issues. There were a few random crashes, but the game auto-saves everywhere, so just launch and continue playing. I've made a step-by-step guide for Hydrophobia years ago in PlayOnLinux, but now with Proton, it just runs without any extra configuration.
