Dr. Professor Scientist's Weapons Testing Facility

Dr. Professor Scientist's Weapons Testing Facility is a wave-based weapon-building game with an extra puzzle game. You choose a major and minor discipline, then assemble a gun from projectiles and modifiers to take on incoming enemies. The Dr. Professor Scientist's faction believes its methods are right, whatever methods it chooses to pursue.

Build your weapon

Your gun can hold up to 15 slots, filled with more than 15 projectile types and 41 modifiers that grow increasingly powerful or wacky. Components have up to five rarities, creating many possible combinations. You can build a conventional weapon or make one that fires exploding cabbages instead of energy shards.

Research and survive

Each cleared wave earns knowledge about building your gun and science points, which you spend to unlock more projectiles and modifiers. These additions help you reach later waves, including the challenge of beating Grand Daddy Crab. New modifiers and projectiles also carry over as unlocks between runs, while the game’s slight roguelite elements let you make progress over repeated attempts.

Change your runs

After beating Grand Daddy Crab, you unlock run modifiers that change each loop. These include monsters moving backwards, a supergun and tiny monsters, as well as positive and negative modifiers to work through on the way to beating the game.

You also unlock desired and undesired slots to influence which components drop. Mark a component as undesired to remove it from the drops, or mark one as desired to favor it.

Play with one hand

The game can be played with one hand, leaving you free to watch your weapon’s input take effect during testing.
