Description:

Empowers you against the alien menace. Model credits: SirCoqaLot plus mOck and MasterCassim.
Sample Collection 
Has a 25% chance to collect a tissue sample from a damaged creep. Once researched, it will provide a 5% bonus vs the race of that creep, through the Xeno Vulnerability Research aura. Maximum bonus per race is 25%. Whenever a different race is attacked, half of the research bonuses against all other races are lost.

Level Bonus:
+1% chance to collect sample
+1% maximum bonus per race
Xeno Vulnerability Research - Aura 
Improves damage vs various creep races for all towers in 280 range. Improvement amount depends on the Sample Collection. Research results are published every 6 seconds and whenever a different race is attacked. Stops working in the Bonus Level.

Note: For this tower, research overrides any and all other race modifications. So the race bonuses of this tower reflect the bonuses given by this aura.
