We can draw some similarities between the protagonist in this clip and the Rwar
1. First off the Rwar might seems invincible going warp 13 with 100+ dmg but eventually it will bleed out even if you’re not there to witness it.
2. The Rwar usually needs to be in close quarters to kill an opponent the closer you get the deadlier the Rwar is.
3. The Rwar needs to have good armor since its dealing with long range instant hit weapons and you’re using short range weapons that take time to utilize.
