Grenade-propelled jump:
Obtain the Horus Feather. Jump and float just above the ground. Look down and throw a grenade. The explosion will push you upwards. This trick may best be put to use on the second to last level (Kilmaat Colony) to skip to the ending. Go to the room relatively early in the level that contains a bridge with lasers on either side. Look up and to the left to find the exit camel. Hover over to the ground right below the camel and use a grenade to propel your character upwards. Hover and move forwards at the height of the jump to reach the camel.

There are a total of 23 team dolls hidden throughout the game. Each doll represents a member of the development team. Find 10 dolls to activate dolphin mode. This allows your character to swim faster and jump out of the water. Find 14 dolls to activate vulture mode. This allows your character to fly.
