Gameplay
The games make use of a unique "vertical cover system", as well as a standard cover system.
The game includes a hover pack, and later, a jetpack, allowing for a quick transition between traditional shooter gameplay and flight. Everything unlocked in the first play through is transferred over to any new play throughs.
Upgrades are purchased using Tech points through a shop at the start of every level before gameplay begins. Tech points are collected from defeated enemies and are hidden throughout the level. There are three different types of Tech points, each with a different value:
- Yellow: 50 points
- Red: 100 points
- Purple: 500 points
