Delta Force uses a voxel based rendering system unlike most other games at the time.
The game features a large set of missions, most of which are set in countryside. The players' objectives differ with each mission. Eliminating all hostile forces is sometimes not the objective, and should the player choose to use up a great deal of his time combating the enemy, he would probably miss his main objective, such as ambushing a convoy. Some objectives which frequently appear are: eliminate all hostile forces, rescue the hostages, intercept an enemy convoy, capture (or kill) an enemy leader, destroy (or recover) certain objects, and ensure the safety of a friendly leader. The player can choose from a variety of weapons. The player's standard loadout is: knife, pistol, main assault weapon（may be chosen from M4+M203, M249 SAW, H&K MP5, M40A1 sniper rifle and Barett Light .50 cal）, grenades, explosives(or double ammunition for the main assault weapon) and a laser designator to call in airstrikes.
Delta Force was praised for emphasizing "gameplay over graphics" in its time.
