1. Upgrade attributes
Players can upgrade bullet, missile, and sub-host capabilities in the upgrade panel. The cost of laser is too large for the moment. Upgrading a bullet can increase the damage of a bullet, while a missile also increases the damage of a missile. Upgrading a sub-host allows players to carry sub-hosts at the beginning of the game and increasing the number of sub-hosts through continuous upgrades, however, the number of sub-hosts depends on your Warship. For example, the default warship Galaxy can only have two racks.
2. Priority upgrade
Because upgrading requires money, it is critical to make proper use of it. Bobby suggested that gamers first upgrade their bullets and sub-hosts to the largest number of sub-hosts currently supported by warships. The reason why they do not upgrade missiles is that the missiles are fired up and down separately, therefore, the probability of hitting an object is much lower than that of a bullet. Most of the time we take a bullet as the primary damage output.
