After some testing by us and the community, we have buffed a few weapons. Some sound effects happened to come down the pipes as well, so we tossed them in.
Mortar - New explosion art and sound
Plasma - Overheats a bit slower, slightly increased accuracy, and new firing sounds
Cluster - Doubled the amount of cluster bombs on detonation and increased the max damage by 10%
Grenade Launcher - Slowed the rate of fire a tad
Boost Grenade - Larger explosion radius (not combos) to help a bit more for knocking players and flag interceptions.
