Edition covered
Original 2011 Crysis 2 campaign. Pictures are publisher images for the original PC Maximum Edition, not Crysis 2 Remastered. Multiplayer bonuses and map packs are separate from the campaign guide.
CELL patrols reward reconnaissance

Human squads use recognizable firing positions, patrols and vehicles. Observe the arrangement before choosing a stealth path or a brief attack from a strong angle.
| Type | Main pressure | Useful response |
|---|---|---|
| CELL infantry | Patrols and ranged gunfire | Tag, flank and break sight |
| CELL vehicles or emplacements | Strong fixed firing lane | Use another angle or heavy equipment |
| Mobile Ceph infantry | Rapid repositioning | Keep space and watch the flank |
| Heavy Ceph | Durability and powerful attacks | Cover, suitable weapons and exposed weak areas |
| Mixed battlefield | Several simultaneous threats | Reduce the closest danger before advancing |
Ceph change the pace of the fight
Alien enemies can close distance and change elevation quickly. Preserve room to move and avoid aiming down one lane while another enemy circles the position.
| Check | Action | Benefit |
|---|---|---|
| Ammunition | Loot useful compatible supplies | Prepare the next engagement |
| Nano Catalyst | Collect safe alien drops | Fund module upgrades |
| Energy | Let the suit refill | Begin the next route ready |
| Modules | Choose for the next approach | Keep the build coherent |
| Objective route | Inspect with the visor | Avoid wandering into another fight unprepared |
Heavy encounters need a protected firing cycle
Use cover between bursts against armored or mechanical threats. Inspect weak areas and the weapons supplied in the arena instead of spending every small-arms round from a stationary exposed position.
Explore the safe aftermath
After the fight, gather ammunition and Nano Catalyst before crossing the next checkpoint boundary. This is the time to alter modules and attachments without a live attack interrupting the decision.
