Submarine 3D simulator vs CCF Challenge

“Submarine 3D Simulator” has been rebuilt with a new game engine and returns as “Submarine 3D Simulator 2.” Take command of a German U-boat during World War II and hunt enemy convoys in this 3D submarine simulation game. Locate enemy ships with the periscope and hydrophone, observe their bearing, speed, distance, and course, then enter the targeting data into the T.D.C. (Torpedo Data Computer) to prepare your torpedo attack. Simply getting close is not enough. Merchant ships take evasive action once you are detected, and escorting destroyers close in to attack your position. When danger approaches, dive deep and shake off the pursuit, then find the convoy again and attack once more. 【Main Features】 ・Command a German U-boat from World War II ・Control diving, surfacing, course, and speed with realistic dials ・Observe targets through the periscope and detect them with the hydrophone ・Calculate firing solutions with the T.D.C. ・Campaign of 5 missions, from your first patrol to a full convoy attack ・Tactical map with contacts, predicted enemy courses, and range rings ・Merchant ships and destroyers that evade, pursue, and drop depth charges ・Time acceleration, auto-save, and continue ・Graphics quality adjusts automatically to your device ・Available in 17 languages ・3D submarine combat above and below the surface 【How to Play】 Dive to periscope depth and use the hydrophone to find the bearing of the convoy. Approach carefully without being detected. When the target is within torpedo range, switch to the periscope view and set the target bearing, speed, distance, and angle on bow in the T.D.C. The computer works out the gyro angle — fire at the best possible moment. Accurate observation and a good firing position are the keys to a hit. Detection, approach, observation, torpedo attack, and escape — experience the tension and tactical decision-making of submarine warfare.

CCF Challenge is a training and education game for learning CPR and ACLS (Advanced Cardiovascular Life Support) through tense, mission-style play. - Missions (BLS) Practice compression rate and depth, hand position, ventilation volume and timing, and AED operation. Track CCF (chest compression fraction - the share of time compressions are performed) in real time, with a performance report at the end. - ACLS Leader Mode (new) You are the team leader. Direct five role-based members - compressions, airway (BVM), drugs (IV/IO), defibrillation, and recording - and run the resuscitation along the AHA ACLS algorithm. Perform rhythm checks every two minutes, defibrillate VF/pVT, and give drugs until ROSC or the resuscitation is stopped. You are scored on both the correctness of your orders and your team's execution quality. - Build your team Earn teammates with high scores. Each member has five skills and a stamina attribute, so team building, role assignment, and rotation all matter. - Clinically correct by design The correct clinical action is always the winning move.
