Grenade-propelled jump:
Obtain the Horus Feather. Jump and float just above the ground. Look down and throw

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.
Team dolls:

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.
