For the Tenet Tetra, this mod will not affect the grenade Alternate Fire.
Projectiles interact strangely with punch through effects - they will not bounce off of enemies, and will often stop after hitting terrain.
It seems that when the projectile hits a surface it decides if it can penetrate the object or not, if it can't, it bounces off the surface. This process goes on as long as the projectile has not penetrated anything yet. The projectile will only punch through what it can penetrate, and after the first penetration, it works just like normal projectile with the bounce effect.
Due to the bullet penetrating thin obstacles at first hit, it is recommended not to use punch through if you plan to shoot the floor or the walls to make full use the bounce effect as it will often penetrate the walls or floor and not stay in the space.
The mod will reduce the range of the projectiles from infinite to 100 meters. Every time the projectile bounces, that range seems to be further decreased. After just two bounces, the projectile will fizzle out after traveling less than 32 meters from the initial firing position.
Shots will not bounce if they are in flight for too long. It is easier to get maximum bounces using Terminal Velocity and other mods that increase flight speed.
Shots can hit the same enemy multiple times. For best results, fire into narrow hallways and crowded areas.
Works very well with Magnetize, allowing each projectile to hit the target all 6 times.
