Warren Marsh’s journey in and around Phoenix-City in REPLACED is a dangerous one full of hazardous obstacles and formidable enemies. While having enough firepower to contend with those enemies is a definite priority, survivability is just as important. Thankfully, the game provides a variety of upgrades to help even the odds.

Some of those upgrades include invaluable ones for your health gauge and the Med-Stim feature, which will help you last through the game’s most uphill battles. Better yet, finding them all gets you an achievement, so here’s where to find all Health and Med-Stim upgrades in REPLACED.

How Do Health and Med-Stim Upgrades Work in REPLACED?

Health upgrades provide you with permanent boosts to your health gauge, which is indicated by a row of red hearts in the top-left corner of the screen. Each upgrade usually adds half a heart, and they’re technically referred to in-game as ‘Genetic Profile’ upgrades.

Meanwhile, Med-Stim upgrades provide boosts to the Med-Stims you use during combat to replenish your health gauge. They can increase their overall effectiveness and also increase the number of Med-Stims you can use during a fight. They’re technically referred to with in-game as terms like ‘Immune Modulator’ or ‘Rechargeable Ampoule’.

Health and Med-Stim Upgrades are vital for surviving combat challenges at every turn in REPLACED. Your vitality doesn’t necessarily matter as much for environmental obstacles in platform sequences, as missing a jump or landing in a hazardous area almost always means death and a checkpoint reset. However, as the game’s combat encounters get more difficult, having as much health and endurance as possible is an absolute necessity.

If you collect all Health and Med-Stim upgrades in the game, you’ll unlock the ‘My Body Is a Machine’ achievement.
