Medkits

In id Software's Doom and Final Doom, these recovery items feature a distinct visual design—originally a white box adorned with a red cross, which was altered in later digital re-releases to a green cross or red pill to comply with Geneva Convention regulations regarding the Red Cross emblem. They are strategically placed alongside smaller stimpacks throughout the non-linear levels, often hidden within secret areas or placed near hazardous environmental obstacles like toxic slime.

For the PlayStation release Spec Ops: Ranger Elite, the implementation of these items reflects the title's tactical realism. Unlike the instant-use mechanics of arcade-style shooters, players must actively select and apply the item from their inventory screen to treat injured squad members. This mechanic introduces a layer of risk, as rangers are vulnerable to enemy fire while administering aid. The inclusion of these healing items in both franchises highlights two distinct philosophies of early 3D game design: the fast-paced, arena-style resource management of id Tech engines, and the deliberate, cover-based survival tactics of military simulations.
