Consumables in Mass Effect Legendary Edition are vital for survival and tactical advantage. Med-Gel is your primary healing tool, allowing Shepard to recover health during combat. It's crucial to manage your Med-Gel reserves, as running out can quickly lead to mission failure. You'll find Med-Gel canisters scattered throughout levels, dropped by defeated enemies, and can also purchase them from vendors. Prioritize using Med-Gel when your health drops to critical levels, but try to avoid overusing it if you can rely on your squadmates' abilities or cover for recovery.
Grenades offer a powerful way to deal area-of-effect damage and disrupt enemy formations. Different types of grenades exist, each with unique effects. Frag grenades deal explosive damage, while Incendiary grenades set enemies ablaze, causing damage over time. EMP grenades are particularly effective against synthetic enemies like Geth and mechs, disabling their shields and abilities. Like Med-Gel, grenades are a finite resource, so use them strategically against groups of enemies or particularly tough single targets. Conserving your grenade supply for critical moments can make a significant difference in challenging encounters.
Beyond Med-Gel and grenades, the galaxy is filled with various mission-critical items. These can range from data logs containing vital intelligence, to unique artifacts that unlock new lore or quests, to keycards or activation codes necessary to progress through specific areas. Always pay attention to your HUD and objective markers to ensure you don't miss these crucial items. Interacting with them is often as simple as walking over them or pressing a button, but their importance cannot be overstated, as they are the linchpins of many story progression points and can unlock significant advantages.
