Getting-Started Advice#
| # |
Tip |
Detail |
| 1 |
Chip away at Veteran |
Some checkpoints on Veteran are brutally hard — take a break after each one |
| 2 |
Flashbangs are god |
On Veteran, flashbangs carry you safely through most of the kill zones |
| 3 |
Cover only lasts a moment |
COD cover is not absolute safety — enemies flank and toss grenades |
| 4 |
Level up in Special Ops first |
Run Special Ops before touching multiplayer — early multiplayer weapon choice is thin |
| 5 |
What prestige keeps |
Achievements, titles, and emblems carry over — weapon and perk unlocks do not |
| 6 |
Shotgun as secondary |
The “Overkill” perk lets you carry two primaries — a shotgun secondary is very practical |
| 7 |
Silencers cut range |
A suppressor hides your shots but shortens the damage falloff distance — mind the situation |
| 8 |
Marathon + SP |
The classic rush combo — unlimited sprint plus high damage |
Difficulty Explained#
| Difficulty |
Detail |
| Easy |
Slow, low-damage enemies — for story-focused players |
| Regular |
The standard experience |
| Hardened |
Higher enemy damage and AI — recommended for a first playthrough |
| Veteran |
One shot kills — some levels demand extreme patience and technique |
Core Veteran techniques:
- Never stay exposed longer than 2 seconds — enemy accuracy is brutally high
- Lead with flashbangs — toss one around every corner
- Know the spawn logic — enemies keep respawning until you push to a certain position
- Shotgun + shield — some tight corridors fall to a riot shield + pistol combo
- Smoke for open ground — cross open areas behind smoke grenades

FAQ#
| Question |
Answer |
| How hard is Veteran, exactly? |
Enemy damage is extreme (2-3 shots and you are down) — expect retries and patience; levels like Khe Sanh and the White House push your technique to the limit |
| Can the “No Russian” mission be skipped? |
Yes — the game shows a content warning at startup and lets you choose to skip it |
| How do I unlock Special Ops? |
Unlocks automatically after finishing the campaign — some challenges require a specific rank |
| What is the strongest multiplayer loadout? |
UMP45 + silencer + Marathon/Stopping Power/Ninja — the widely accepted best all-round combo |
| Is prestige worth it? |
All unlocks reset but you earn custom titles and emblems — purely for bragging rights |
| Can PC still play online? |
Steam matchmaking still works but with fewer players — community servers are recommended |
| Is full achievement completion hard? |
The hardest is three-starring every Special Ops mission — it demands exceptional coordination and skill |
| Best killstreak combination? |
Beginners: UAV (3) + Care Package (4) + Harrier (9); veterans: Predator (5) + Harrier (9) + Nuke (25) |
| Which Special Ops mission is hardest? |
All three Charlie-tier missions are brutal — especially the Echo tier and “Snatch & Grab” — and demand tight two-player coordination |
- Valorant — a tactical competitive FPS built on precise gunplay
- Team Fortress 2 — the classic class-based team shooter
- PUBG — the shooter that pioneered the battle royale genre
- Battlefield 6 — large-scale modern military warfare in the same blockbuster mold
- Delta Force — a modern military shooter with classic large-scale modes
