Blake will be injured along the way, the only way to completely prevent this is with the God Mode cheats. Health Items will restore damage done to him up to 100%. The different items all provide various amounts of health.
Health Items[]
Health items will not heal above 100%, even if the item provides that much health. For example, collecting a First Aid bag while at 90% health will cause the item to only give 10% health. Water puddles can only be used for healing if the player's health is at or below 15%.
| Item | Heal Percentage | Image |
|---|---|---|
| Water Puddle | 5% | 
|
| Fresh Water | 5% | 
|
| Candy Bar | 8% | 
|
| Sandwich | 10% | 
|
| Raw Meat | 15% | 
|
| Steak | 20% | 
|
| First Aid Kit | 30% |

Food Units[]
In addition to health items the game contains special wallpaper walls called "Food Units", which when Blake uses a token, he is healed a fixed amount. Food Units eventually will break down and become unusable after being fed a certain number of tokens. Tokens are found, dropped by enemies or given by Bio Techs.
