The Peacekeeper

Defend Your Trench Against Wave After Wave
The Peacekeeper is an action shooting and defense game where you control a heavily armed soldier standing inside a trench. Despite the peaceful title, your job involves fighting large groups of attackers that keep advancing toward your position. You need to survive each wave and stop the enemies before they overwhelm your defense.
The soldier can move vertically through the trench. This lets you line up shots with enemies appearing at different heights and move away from incoming attacks.
Aim and Fire From Cover
You use the mouse to aim and fire your weapon. W, A, S, and D or the arrow keys move the Peacekeeper around the dugout.
An important part of the game is knowing when not to shoot. Releasing the mouse lets your character crouch down inside the trench. This can protect him from enemy fire.
Standing up gives you a chance to attack, but it also leaves you exposed. Ducking at the right moment can save health when several enemies fire together.
Use Grenades Against Groups
Normal gunfire works well against many attackers, but grenades give you another option when the battlefield becomes crowded.
Enemies become more dangerous as the waves continue. Some can take more punishment, while larger groups put greater pressure on your position.
Using stronger attacks at useful moments can prevent several enemies from reaching the trench together.
Upgrade Between Attacks
After completing a wave, you can spend your earnings on improvements. Upgrades include stronger armor, more health, and increased bullet damage.
These improvements become important because later waves are tougher than the opening attacks. Better damage helps remove enemies faster, while stronger protection gives you more room for mistakes.
The Peacekeeper mixes shooting with simple defense planning. Move through the trench, aim carefully, duck when bullets come toward you, use grenades when the enemy gathers together, and improve your equipment after each successful wave.
Surviving for a long time requires more than holding down the fire button. Knowing when to attack and when to take cover becomes just as important as accurate shooting.
