Overthrust
Six axes. One way out.
A combat flight game inspired by the freedom of classic six-axis shooters. Explore seven missions, battle in open space and twisting passages, and strike the enemy's power source. In escape missions, find your way out before the countdown reaches zero.
Previously known as Riftburn. The new name keeps the same freedom to fly, fight and explore.
BETA 3 (Rel. 6.1025) · Free to play · Windows 64-bit
Seven missions, seven kinds of flying
From mountain valleys to the depths of Oumuamua
Every mission is available from the start. Explore at your own pace; destroying the power source starts the escape timer in Kestrel, the Nest and Oumuamua.
Fight beneath the canopy.
Fly between floating islands, descend into forests and hunt concealed defenders. Destroy the radar and clear every opponent.
Use the rocks as cover.
Clear 30 hostiles across three clusters in open space. Search among rotating asteroids for repairs and Hellfire ammunition.
Choose your route underground.
Approach from orbit, enter the planet and explore seven interconnected alien chambers. Destroy the Nest heart, then escape to space within 150 seconds.
Find what lies below.
Enter an immense silo, neutralize the marked human pod and find your way back to the surface. Explore without an escape countdown.
Uncover the probe's secret.
Explore the mysterious object, destroy its central power core and escape to space before the probe explodes in 180 seconds.
Follow the valleys. Clear the caves.
Battle 120 opponents across a living mountain landscape. Follow the river, search for supplies and explore caves for the remaining defenders.
