Airstrike 1 200 N/A 30 Also, all barrels and pressure tanks in the game are shootable explosives with specifications:
Name Radius(m) Damage Barrel 30 150 Pressure Tank 50 300 -
Waypoints
8 waypoints are provided for players to navigate the map and switch weapons associated with waypoints
-
Rounds
Protect your waypoints from monsters!
In each round, a new monster will be generated every t seconds (t: a random number between 1 and 2) and the monster type is determined by probability attribute of monster attackers. The target of monsters is the nearest existent waypoint and the waypoint will be destroyed once one monster arrives at its location. The player will be not able to use weapons associated with lost waypoints any more.
In the nth round:
- amount of monsters = 2 x n
- monster speed = initial speed x n
If the player eliminates all monsters, then a new round starts and all the weapons lost in the last round will resume with full ammunition. While there is no limit of rounds, players typically are not able to survive more than 10 rounds since there will be a huge number of monsters with really high speed.
