Silent Storm engine

[9][10] Reviewer Greg Kasavin commented that "pray and spray" tactics are quite viable, as the game uses silhouettes to mark enemies' estimated positions when they happen to lie out of eyesight but within earshot.

[9] The player's units gain experience points over time for completing actions, which can later be spent on purchasing new skills and abilities.

[10] Also praised were the quality of its graphics[13][14] and weapon and environmental sounds,[11] though these sentiments were tempered as the engine began to age.

[4][9] Criticisms include the engine not taking into account the relative position of objects in 3-dimensional space when making selections using the mouse.

[10][16] Finally, the engine has been criticized for the length of time required for the artificial intelligence to complete its turns,[11][15] a lack of any multiplayer support[9] and the uncooperativeness of its camera controls.
