Rinoceronte lines now! Climb the branches and catapult your progress from May 5 at 07:00 CEST through June 5 at 07:00 CEST (UTC+2).
The XSTB-1 line stands out from most with a hydropneumatic system that lets you increase your already decent vertical gun angles. But don’t be fooled. The Tier X STB-1 also has a few extra tricks up its sleeve. For instance, it boasts an incredible rate of fire and solid damage values per shot. In fact, it has one of the best DPM values in the entire game—3,042 HP/min! It’s best used when hiding behind a ridge and raining destruction on unsuspecting enemies below. Plan your route of attack today!
The XRinoceronte will offer days and nights of romance with its elegant beauty and unconventional turret. The unique shape and low profile offer great camouflage attributes and make it a tricky opponent to hit at range. Pick out hills, natural defenses, and snug spots where you can put the great gun depression and sloping capabilities to good use. Firepower-wise, the innovative 3-shot autoreloader offers solid burst and alpha damage, penetration, aiming time, and accuracy. The rapid APCR shells prove particularly effective when firing from medium to long range. So, why not take this Italian stallion for a spin?
Don’t forget that you can purchase an extra boost in the Premium Shop or in-game if you want to speed things up!

Thanks, already got the STB-1, and the Rinoceronte isn’t worth getting over the tier 9, afaik.
