Such is the case of the Delta Force series, which always emphasized tactics instead of brute force and made it extra difficult for players to get through the levels using the classical approach. The Delta team is back in action yet again Contrarily, if you do not take the appropriate measures to shield yourself from the enemy fire and you just waltz into their base, things quickly turn badly and you are greeted by the game over screen. Tactical shooters take into consideration much more than how big your gun is and how many bullets can it output each second.
