Radar-Usage: To find bomb, to locate teammates, if you hear footsteps and nothing is on your radar: its the enemy. Common Sense.
A lot of player: T's will rush short, mid, A, Tunnels. I would pre-aim and check several times before carrying on. It's obvious and common sense.
No Suspicious kills: Some average gameplay. Nothing really special tbh. No suspicious parts. Tunnels was clean. Teammate dies, you will notice from footsteps and direction of death OF teammate where the enemy should be. So you preaim...Common Sense.
There where multiple enemies in tunnel since you can hear them all. Teammates where locking in from B and they where coming from T Spawn. Where else are the terrorists going to run to?
Clean..
