P.R.O.B.E is a fast-paced, unforgiving “tunnel-runner”, loosely set in our Ultimate Space Commando universe. You are tasked with the field testing of a recently prototyped reconnaissance unit, the Pioneering Remote Orb, with which you enter the tunnels of an alien-infested mining facility, both to evaluate the P.R.O.B.E’s capabilities and your own skills…
It is a “classic”, deliberately minimalist arcade game, where your only goal (at least currently) is to earn the most score and reach the furthest level. On your run you will encounter obstacles, dangers and also useful stuff–everything has its role or purpose. Energy balls grant some energy for your shields, but give a speed boost that may be lethal if you’re not careful. You may attempt to crack special crates for a bonus, but doing so you may die if your skills fail. You need to carefully manage your health and energy to reach far.
You can also collect crystals to upgrade your P.R.O.B.E between levels or to retry a level–spend them wisely!
