- You will hear players call the "SSG" the Scout, and the "SG" the Krieg.
- Even the slightest movement will affect your aim. To get perfect first shot aim, you must be still.
- Each weapon affects your running speed when equipped. The knife is fastest, next to grenades, then pistols. The heavier the gun, the slower you'll roll.
- Some guns require you to take pauses between shots to regain perfect accuracy, like the Deagle.

P.S. Ever play Left 4 Dead? The gunplay in those games act very similarly to this game. Movement ruins aim, you want to aim for the head, controlled bursts are best, and side-stepping to remain mobile and fire is still prevalent.

- The ranked modes in this game are: Competitive, Danger Zone, and Wingman.
- In modes where you spend money for items, your cash carries over to the next round. DON'T spend everything every single round. You'll never be able to afford good gear!
- All other modes have no ranking system, and is purely divided by prime and non-prime players.
- Prime players can face prime and/or non-prime players, but non-prime players will never play prime players in VALVe's official matchmaking.
- Non-prime players you encounter are more likely to be hackers, cheaters, or unlikable in general.
- Competitive and Wingman share similar rank systems (image below), whilst Danger Zone does not function anywhere near the same as Competitive/Wingman's rank system.
- Wingman is a ranked 2 vs 2 mode in limited areas of full size competitive maps and bonus maps.
- Danger Zone is a battle royale mode with cash and upgrade mechanics included.
- VALVe's competitive matchmaking is a 5v5 mode of 15 rounds on Terrorist and 15 rounds on Counter-Terrorists for each team respectfully, allowing for a maximum of 30 rounds.
