Void Sentinel

Void Sentinel takes place on an electromagnetic grid map that automatically expands in size after each wave of Commanders is eliminated. Enemies appear from gates and head straight towards the Energy Core in the center. Players are not allowed to build within the forbidden zone around the Core. Enemies come in several types: regular, self-healing shields (armor must be broken before health can be reduced), and stealth (only revealed when attacked). The Energy Core has an automatic self-defense system to fire back at enemies at close range; however, it's important to note that enemy Commanders deal 10 times more damage to the Core than regular enemies. Difficulty and enemy health increase with each wave of attack. The game begins by selecting the difficulty: Easy (15 waves), Medium (25 waves), or Hard (40 waves). The system provides the ability to adjust the match speed (1x, 2x, 4x) to optimize strategy. Before each wave, there is a 10-second preparation period to observe the enemy's expected path. The system will display a clear visual warning when the countdown timer is less than 3 seconds. The tower will automatically target the nearest enemy. Every 10 waves, a powerful enemy commander will appear. After each wave, the player receives gold coins and energy crystals. Win/Loss Conditions: Win: Overcome all attack waves; Loss: The Energy Core is completely destroyed. Items purchased with gold coins are available in the left column: Impact (instantly eliminates weak enemies), Overload (doubles the attack power of the entire tower with a glowing effect when activated), Repair (restores the Core's health). Regarding the upgrade mechanism: During the match, use gold coins to upgrade the tower to a maximum of level 5 or sell the tower to recover 50% of the total investment. Players can also use crystals to quickly unlock new tower types during the game. Permanent upgrades at the main store increase core technology stats. Player records will be shown on the leaderboard and all progress is automatically saved.
