Counter Strike: Game Overview
Counter Strike, often abbreviated as CS, is a legendary first-person shooter (FPS) franchise that revolutionized competitive gaming. Originally developed as a mod for Half-Life in 1999, the game has evolved through multiple iterations including Counter Strike 1.6, Counter Strike: Source, Counter Strike: Global Offensive (CS:GO), and the latest Counter Strike 2 released in 2023.

Advanced Strategies & Game Tips
Mastering Counter Strike requires more than just good aim. Here are professional-level strategies used by top players and teams.
Economic Management
The in-game economy is arguably as important as shooting skills. Key principles include:
- Save Rounds: When economically disadvantaged, purchase only pistols or save completely
- Force Buys: Sometimes purchasing SMGs or upgraded pistols can swing momentum
- Full Buys Rifle, armor, helmet, and grenades (approximately $4,200-$4,700)
Pro Tip:
After winning the pistol round, invest in SMGs rather than rifles to maintain economic advantage while capitalizing on opponents' weaker buys.

| Map | Critical CT Positions | Key T Entries |
|---|---|---|
| Dust II | Long Doors, A Site, B Tunnel | Long A, Mid to B, Lower Tunnel |
