A mouse and keyboard is required to play. A mouse wheel is not required but it helps out! The controls are relatively easy to pick up as they are similar to popular PC games (like Counter-Strike or Call of Duty).
Use the keyboard to control the player and the mouse to control your current weapon/item.
This is your typical Deathmatch game mode; kill the enemy to reach the score limit! You can set the game options to your liking. The first team to reach the score limit will win. If time expires, the team with the highest amount of kills will win (if they are tied, then the game will be a draw). You can also select your default weapon for Deathmatch. If you select random, you will receive a random weapon each time you respawn. Otherwise you will spawn with your weapon of choice each time. Your health regenerates at a rate of 500%.
The Defender game mode combines survival with tactics. You must prevent the objective from being destroyed by the enemy, but you only have 3 lives! Your health does regenerate, but you cannot gain more lives, and you cannot restore the objective's health.
The Defender game mode does not have a wave limit and will go on for as long as you can survive. Gain money and XP though getting kills and completing waves. Purchase weapons, items and upgrades from the store crate.
The Undead Survival game mode is your typical survival game mode. Hold out as long as possible against the limitless waves of undead creatures.
The Undead Survival game mode does not have a wave limit and will go on for as long as you can survive. Gain money and XP though getting kills and completing waves. Purchase weapons, items and upgrades from the store crate.
The objective of the Chaos Arena game mode is to rack up as many kills as possible. You can take up to 3 weapons with you into the arena. Max out your XP to obtain friendly air support and a small amount of health restoration.
When your XP is maxed, there is a 25% chance that you will receive an Osprey airdrop. Otherwise you will receive an ammo airdrop.
XP reward: Health restoration + air support
